Donaghy/Donaghey

39

Controlling extensive territories stretching from Raphoe to Ballyshannon they were the chief marshals in the army of O’Donnell, Prince of Tirconnell.
Gillespie

48

Irish and Scots Gaelic. This name originally meant son of the servant of the Bishop. In Ireland Gillespie originated as a County Down sept which settled, at an early period, in County Donegal where they became hereditary tenants of the church lands of Kilcar. In Scotland the Gillespies were a sept of Clan MacPherson. By translation the name also became Bishop.
Hamilton

14

Scottish. Derived from the Yorkshire place name of Hambleton, meaning crooked hill, this surname was introduced to Scotland in the 13th century by a Norman family from Leicestershire. In the 14th century the Hamiltons were granted the lands of Cadzow in Lanarkshire by Robert the Bruce. Hamilton is a name very much associated with the Scottish ‘undertakers’ or landowners who were granted large estates in Counties Armagh, Fermanagh and Tyrone at the time of the 17th century Plantation of Ulster.
Harkin

7

By the 17th century they had established themselves in Inishowen, County Donegal and in County Derry, west of the River Roe. The Hegartys were sub-lords to the O’Neills.
Johnston

44

Scottish. Strictly speaking Johnson and Johnston are two distinct surnames; the former meaning son of John and the latter John’s town. The two names, however, are now indistinguishable one from the other. The Johnstones were one of the great riding clans of the Scottish Borders who settled in Dumfriesshire in the lands of Johnstone in the 12th century. During the Plantation of Ulster many of them settled in Fermanagh. Furthermore septs of Clan Gunn in Caithness and of Clan Donald in Glencoe anglicised their name to Johnson and Johnston. In Ireland a number of septs including McKeown and McShane anglicised their name to both Johnson and Johnston.
Kelly

4

Irish. At least seven distinct septs of the name established themselves in Ireland, the most powerful of which ruled over a territory which included east Galway and south Roscommon. In Ulster, a Kelly sept, claiming descent from Colla, the 4th century King of Ulster, was based in south Derry. Kelly was known as a surname in Scotland long before the 19th century immigration really established the name there; there was a Kelly sept attached to Clan Donald.
Logue

51

Irish. A County Galway sept, whose name originally meant descendant of the devotee of Maodhog, who migrated at an early date to Derry and Donegal. The name is now rare outside these two counties. Mulvogue was another form of the anglicisation of this name. In Donegal Logue was in some cases changed to Molloy, an important sept in counties Offaly and Roscommon.
Lynch

11

Irish. Derived from the personal name meaning mariner there were several septs of the name including one based in north Antrim and Derry. In medieval Galway Lynchs of Anglo-Norman origin were all-powerful. In England Lynch derived as a local name for someone who lived by a hill.
Martin

59

Can be of English, Scottish or Irish origin. In Ireland it may be an abbreviation of the County Tyrone sept name of McMartin and of the County Fermanagh sept name of McGilmartin. In England the personal name Martin became, at an early date, a popular surname while in Scotland septs of the name were attached to Clan Cameron in Inverness-shire and to Clan Donald in Skye.
McBride

60

Irish. Meaning son of the devotee of Brigid this County Donegal sept, who were based at Gweedore, were hereditary tenants of the church lands of Raymunterdoney. Scots Gaelic. This sept of Clan Donald, who were based on Arran Island, trace their descent from Gillebride, father of Somerled, the 12th century Lord of Argyll.
McCafferty

33

Irish. Meaning son of the horse rider this sept originated in County Donegal as a branch of the O’Donnells. The name has become confused with McCaffrey, a sept which traces its decent from Donn Carrach Maguire, King of Fermanagh, who died in 1302.

21

Scots Gaelic. Meaning son of Colin the McCallions were the galloglasses (mercenary soldiers) of Clan Campbell of Argyll. In the 16th century they came to Donegal to fight for the O’Donnells.

23

Irish. This County Derry sept is very much associated with the Dungiven area. They were a branch of the O’Kanes, tracing their descent from the 12th century Bloskey O’Cahan.
McDaid

10

Irish. This County Donegal sept was a branch of the Dohertys. Meaning son of David they take their name from the O’Doherty chief of that name who died in 1208. In a few cases McDaid may be a variant of the Scottish clan name Davidson.
McDermott

26

Irish. This County Roscommon sept was a branch of the O’Connors, Kings of Connaught before the Norman invasions of the 12th century. A few may be of Scottish origin as in Perthshire there was a Clan Campbell sept of this name.

McGinley

56

Irish. This County Donegal sept played an important part in church affairs in the Diocese of Raphoe. The name is often confused with McKinley. In Scotland McKinley septs belonged to Clans Buchanan, Farquharson, MacFarlane and Stewart of Appin.
McGowan

32

Irish. Meaning son of the smith the most powerful sept of this name originated in County Cavan. Other septs of the name were also based at Inishmacsaint, County Donegal and at Clogher, County Tyrone. Scots Gaelic. As the maker of arms the smith was an important hereditary position in each clan. As a consequence the surname Smith was associated with most clans. This surname, more than any other, has suffered at the hands of anglicisation. Many Smiths in Ulster today were originally McGowan.
McIntyre

58

Scots Gaelic. Meaning son of the carpenter this clan settled at Lorn in Argyllshire from the Hebrides around 1400. A branch of the family were hereditary pipers to the chiefs of Clan Menzie. The name has become much confused with McAteer, a County Armagh sept, whose name has also been changed to McIntyre.

McLaughlin

2

Irish. The second most popular name in Derry. Derived from the Norse personal name Lachlann this County Donegal sept can trace its lineage to Eoghan, son of the 5th century High King of Ireland, Niall of the Nine Hostages. In the 12th century the McLaughlins, from their Inishowen homeland, were High Kings of Ireland and patrons of the monastic settlement in Derry. From the mid-13th century the O’Neills of Tyrone ousted the McLaughlins as the leading power in Ulster. Some may be of Scottish descent from Clan MacLachlan of Argyll.
Millar/Miller

34

English and Scottish. As every manor or estate had its miller this occupational surname sprang up all over England and Scotland. Millar is usually regarded as the Scottish spelling of the name.
Mitchell

49

Can be of English, Scottish or Irish origin. Derived from the Hebrew personal name Michael, and in a few cases from a nickname meaning ‘big’, Mitchell became very numerous throughout England and Scotland. In Northeast Scotland the Mitchells were a sept of Clan Innes. Furthermore the Highland Scottish name of McMichael, septs of Clan Stewart of Appin and Clan Stewart of Galloway, was frequently anglicised to Mitchell. In Ireland, and in County Donegal especially, the County Roscommon sept name of Mulvihill was anglicised to Mitchell.
Moore

5

Can be of English, Scottish or Irish origin. In England and Scotland the name derived from the personal name More, meaning Moor (i.e. the Muslim people of Northwest Africa) or from a local name for someone who lived on or near moorland. Moore became widespread as a surname throughout England and Scotland. In Scotland the name was also known as More and Muir. The Mores were a sept of Clan Leslie while the Muirs were a sept of Clan Campbell. In Ireland the O’Mores were the leading sept of the Seven Septs of Leix.
Moran

50

Irish. In the Province of Connaught there were four distinct septs of this name. In addition the County Fermanagh sept of McMorran has become Moran. Moran is also a recorded variant of Morahan which originated in Offaly and Leitrim. In some cases, as Morrin, it may be a Huguenot name. Many Huguenots fled to Ulster from France in the late 17th century in the face of persecution by Louis XIV.
Morrison

28

Irish. A County Donegal sept who were hereditary tenants of the church lands of Clonmany adopted this English name which meant son of Maurice. Scots Gaelic. Claiming descent from a Norse family shipwrecked on the Island of Lewis Clan Morrison, from their seat at Habost on the northern tip of the Isle of Lewis, became sub-lords to the MacLeods.
Mullan/Mullen/Mullin

24

Irish. Meaning descendant of the bald one and tracing their descent from the 5th century High King of Ireland, Niall of the Nine Hostages, the O’Mullan sept originated in the Laggan district of east Donegal. As a member of Clan Connor they accompanied the O’Kanes in their invasion and settlement of north Derry in the 12th century. Confusion is caused by the fact that the majority of Scottish Macmillans adopted the surname of McMullan, which, like O’Mullan, was frequently shortened to Mullan.
Murray

45

Scots Gaelic. Taking their name from the northern province of Moray this clan acquired its territory in the 12th century from David I. Irish. Derived from a given name meaning mariner several septs of this name originated in counties Cork, Down, Leitrim and Roscommon.
O’Doherty

30

Irish. This County Donegal sept, which originated in Raphoe but settled in Inishowen from the 14th century, can trace their lineage to Conall Gulban, son of the 5th century High King of Ireland, Niall of the Nine Hostages. They ruled Inishowen until the arrival of an English army at Derry in 1600. An O’Doherty-led rebellion, which included the ransacking of Derry in 1608, helped pave the way for the Plantation of Ulster. This name is also anglicised as Doherty.
O’Donnell

13

Irish. Taking their name from Domhnall, who died in 901, and tracing their descent from Conall Gulban, son of the 5th century High King of Ireland, Niall of the Nine Hostages, this sept, from their base around Kilmacrenan, County Donegal, rose in importance from the 13th century to the position of overlords of Donegal. The O’Donnells, alongside the O’Neills, led the Ulster Rebellion of 1594-1603 against English encroachment.
O’Kane

29

Irish. The sept of O’Kane or O’Cahan can trace their lineage to Eoghan, son of the 5th century High King of Ireland, Niall of the Nine Hostages. Originating in the Laggan district of County Donegal the O’Kanes, who were the leading sept of Clan Connor, settled in the the Dungiven area, County Derry from the 10th century. By the 12th century they had established themselves in County Derry from the Foyle to Bann rivers and they had gained the privilege of inaugurating the chief of the O’Neills.
O’Neill

36

Irish. Tracing their descent from Eoghan, son of the 5th century High King of Ireland, Niall of the Nine Hostages, this sept has one of the oldest surnames in Ireland. It has been in continuous use since King Domhnall in the 10th century adopted the name of his grandfather Niall, Black Knee. The senior branch of this sept, the O’Neills of Tyrone, were frequently High Kings of Ireland and in the 16th century they were the leaders of Gaelic resistance to English attempts to pacify Ireland. A junior branch established themselves in County Antrim in the 14th century and from their seat at Shane’s Castle became known as the Clandeboy O’Neills.
Porter

57

English and Scottish. This occupational name can have three meanings, the most likely one being a doorkeeper. In the Middle Ages the office of porter was a very important one in both castle and monastery. In some cases Porter referred to a person who could be hired to carry baggage while in Scotland it had an additional meaning of ferryman. Porter was first recorded in Ireland in the 13th century.
Quigley

17

Irish. By the end of the 16th century this sept, which originated in County Mayo, had become dispersed with its main concentration located in Counties Derry and Donegal. A sept called Quigley also originated in the Inishowen peninsula, County Donegal.
Robinson

53

Derived originally from the personal name Robert, a popular Old English personal name, Robinson is generally regarded as an English name and Robertson as a Scottish one. In Ulster, however, Robertson and Robinson have lost this neat distinction.
Simpson

37

English and Scottish. Meaning son of Simon it was derived from the Old Testament name Simeon which became a very popular medieval first name. In Devon in the 13th century three places named Simpson gave rise to the surname there. In the Highlands of Scotland McKimmie, a sept of Clan Fraser, whose name meant son of Simon, was anglicised to Simpson. Simpson has been recorded in Ulster since the 17th century.
Smith

15

Smith, also spelt Smyth, can be of English, Scottish or Irish origin. It is the commonest surname in England, Scotland, Wales and Ulster. This occupational name sprang up all over England wherever there was a smith (such as blacksmith, gunsmith, goldsmith, etc.). In Scotland and Ireland Smith was a further anglicisation of McGowan.
Stewart

38

Scottish. Derived from the Old English occupational name of Steward who was the keeper of a household. As every Bishop or Landlord had his Steward the name sprang up all over Scotland. From the 12th century Walter, the High Steward of the Royal household, who was responsible for the collection of taxes and the administration of justice, descended the Scottish Royal family of Stewart. Clan Stewart, which also traces its descent from the above Walter, later divided into separate clans: the Stewarts of Appin; of Atholl; of Bute; and of Galloway. Nine of the 59 Scottish ‘undertakers’ or landowners granted lands in the 17th century Plantation of Ulster were Stewarts.
Taylor

43

English and Scottish. Derived from the occupational name of tailor. On the English side of the Scottish Borders the Tailors were one of the riding clans. In the Lowlands of Scotland the name was first recorded in the late 13th century while in the Highlands the Taylors or McTaylors were a sept of Clan Cameron in Argyllshire. The name was well known in Ireland from the 14th century but it was the 17th century Plantation of Ulster which established the name in great numbers in counties Antrim, Down and Derry.
Thompson

20

English and Scottish. Meaning son of Thomas this surname, spelt as Thompson, was the 15th commonest name in England and, as Thomson, was the 5th commonest in Scotland. This distinction in spelling, however, was not perpetuated in Ulster. The Thomsons were one of the lesser riding clans of the Scottish Borders; many of whom settled in County Fermanagh during the 17th century Plantation of Ulster. In the Highlands of Scotland a number of distinct septs of McThomas anglicised their name to Thomson and to McCombe and Holmes.
Walker

41

English and Scottish. In the North and West of England Walker derived as an occupational name for a fuller. In the Middle Ages it was the fuller’s job to scour and thicken raw cloth by ‘walking’ or trampling upon it in a trough filled with water. Walker also became widespread in Scotland where it was first recorded in the early 14th century. In Ireland the name is most common in counties Antrim, Down and Derry.
Ward

52

In England this name derived as an occupational name for a watchman or guard. Most Wards in Ireland, however, are of Gaelic Irish origin. Meaning son of the bard, and also anglicised as McAward and McWard, septs of this name were hereditary poets to both the O’Kellys of Galway and the O’Donnells of Donegal. The Wards of Donegal were based at Lettermacaward near Glenties. In Scotland McWard generally became Baird but not Ward.
Wilson

25

English and Scottish. Derived from the Old German personal name William which was introduced to Britain by the Normans. It is estimated that 80% of Ulster Wilsons are of Scottish descent; Wilson was a common name throughout the Lowlands of Scotland. Furthermore the Wilsons were septs of Clan Gunn in Caithness and Sutherland and of Clan Innes in Banffshire.
