Mac MaolŠin

Origins of the surname "Mac Maoláin"

Mac Maoláin

Mac Maoláin as a surname, evolved from the old Irish Gaelic root form Maelan  circa  700-900 AD, and later middle Irish Gaelic variant forms Maoláin; Mailin circa 900-1200AD,  as verified in numerous Irish annal entries spanning hundreds of years.

One additional possibility  predating these monastic entries is found in a translation of the extract text of the narrative regarding the "Aghascrebagh Ogham Stone" of Co. Tyrone:

"one of the very few Ogam stones in the north of Ireland, and almost certainly a standing-stone before Ogam was cut into it. The stone, 1.2 metres high, has been re-erected. The much-worn inscription has been interpreted as DOTETTO MAQI MAGLANI - of which only seven letters can now be read"

MAQI according to experts is said to be one the earliest form of Mac = son of, leaving some researchers convinced this ogham stone text is referencing a mac Maelan 

These origin variants became anglicized in the modern era as Mullan/Mullen and "son of"= MacMullan, MacMullen, MacMoylan, later shortened to McMullan, McMullen, McMullin and McMoylan.

Existence of the early Irish variant forms of Mac Maoláin, Mic Maoláin, Mhic Mhaoláin, Mec Mellain and Mec Maoilin, are verified by: ancient Irish townland's established in the locales that these families inhabited; diversified Irish annal entries recorded by clerics located in different areas, spanning several centuries; specific hand written notes found in the charter section of the "Book of Kells"; and specific individuals named in the ecclesiastic histories of specific dioceses in several provinces of Ireland.

This factual information highlights the diverse origins and reality of several unrelated families eventually adopting this forename as a surname. More importantly it exposes the simplistic research efforts adopted by consumer crest marketing companies, who simply offer questionable analysis about where this surname factually first emerged.

Forenames Maelán, Maolán, Maoláin, Meallain and the collateral medieval surname Mac Maoláin (son of), surface in terms of historic identification, in some of the earliest records of tribal clusters that have been identified by Irish research projects.

Extracted from ancient texts, affiliated references where a significant chieftain used this forename include entries found sequentially with: the Fir Gallion;  the Ui Bairrche and their mercenary allies of Clanna Rory (Laighsi); the Laigin (pronounced Lein/Lyne) and downstream dynastic pedigrees posted for: Ui Failghe; Ui Dunlaigne; Ui Fergusa and Clan Donnchada. 

These territorial dynasties emerged over periods in excess of several thousand years, reshaped by conquest and defeat. They produced several diverse variants of the original forename Maelan, recorded in several different locations for clearly unrelated families (septs)

It was also found recorded in diverse monastic sites such as Ceanannus (Meath), Clonmacnoise (Offaly), Clones (Monaghan), Swords (Dublin) Clonfert, Kilnamanagh (Roscommon), Kilmactranny (Sligo), Daire (Derry) Collumcille and Aghohill Antrim.

It was these monastic occupational records which contributed to the later more frequent transcribed use of the tonsured form (Maolain= bald) instead of Maelan (=hillock or height). Consequently it is used in recording those linked to tribal events as well as monastic.

The descending form Mac Maelan to Mac Maolain on the other hand was well documented for Mac Maolain Leinster.

The variants Maolain (Mullan, Mullen) and Mac Maolain would eventually became the most common form adopted in Ireland by dispersed regional scribes recording the historic events of their day.

Tracking ancient pedigree's or territorial population groups where a prominent individual named Maelan & Mc was listed,  will suggest as expected, several different cultural and topographic relationships, with links to:

the Eoghanachta, sons of (Cormac Gaileang); 

the Dal Riada Clanna Rory sons of (Fergus Gaileang); and

the Laigin, Cathoir Mor Ui Failge sons of (Sil Cormaic Gaileang).

Where these tribal references appear in historic renderings, they often include comments suggesting mythologic connections to ancieint dieties, examples being Lugh, Nauda and the mystic Tauth De Dannan.

Specific surname families (clearly more than one) that have been identified in more recently published genealogical works include Irish Genealogical Society's history of Clanna-Rory, with MacMullen noted on page 16 and migration of Fergus Gaileanga to "Teffia"on page 86, the "Ethnology of the Gael" a research project by  C. Thomas Cairney, listing O'Mullan on pages 78, 82 and 87 as of the Laigin and loated in Galway, plus John O'Hart "Irish Pedigrees, or Origin and Stem of the Irish Nation 1892, listing the Leinster sept Mullen of the Ui Failge dynastic group.


Many different pedigrees and topographic suggestions are linked to this surname and the history surrounding it. They verify as genetic studies have, that several distinct and separate families adopted bore this surname over many centuries.

Most modern historians wisely caution that the very ancient portions of pedigrees conceptually should be read with a view of likely only being completely reliable from about the 9th century onward, due to constant shifts in dynastic affiliations of earlier times, which produced many assigned and some false/corrupted versions.

Below are listed all the possible pedigrees connected back on Irish evolutionary pathways where a prominent family whose dominant male in that particular territorial cluster, may have had a forename which later evolved to a Mullan, Mullen, McMullen.

The 1ST  annals recorded Mac Maoláin is found in the pedigree of the Gaileanga Mora

During the 10th century forenames evolved to surnames.For Maelan/Maolain (Mullen) of Leinster, the descendant form, Mac Maoláin emerged in records commencing 11th century for a family associated at that time with Mide (Meath) Luighne and Gaileanga tribal clusters. These population groups were extant in physical territories referenced as Morgallion and Brega.

This map circa 700 AD of the "Breifne Region" illustrates the topographical locales of these Gaileanga Mora and Mide/Brega Luighne families (Castlerahan & Clankee Cavan; Lune Mide; Lower Kells and Morgallion, Meath.

These are the predominant "annals supported" patrimonial locations for that family who adopted 1st the eventual surname of Mac Maoláin:

Mac Maoláin (Gaileanga Mora and Brega) 

This line is identified and discussed,  by variant historians as culturally linked in very early times to either: Munster and the mythological sons of Cian (Cormac Gaileang); or alternately the Red Branch Knights of Clanna Rory (Fergus Gaileang).

Suggestions are that they later emerged in the Dunmore area of  Magh Seola Galway, branching 7th century to a new territory called Gaileanga  Mora in Cavan and Meath. A Chieftain Lorcan or Leochain  (Lorkin, Larkin, Loughan, Logan, Lohan) circa 10th Century, is identified in the Irish Annals as territorial Lord of these Gaileanga of Mide, Cavan and Brega.  1037AD, Laidcenn (variant Laidhgnen anglicised Lynan), is listed variantly by scribes located in different annals/locations as either the son of Maolán, or grandson of Eccnigh Ui Leochain (translates Lohan) or alternatley Ui Lorcan (translates Larkin).

Lynan became  the king of the Gaileanga Mora,  married the daughter of the Gott (son of Conchhubar Maelseachlain) king of Uisneach=Westmeath Southern Ui Neill) and travelled with her to Rome on a pilgramage.

Lynan earlier (circa 1025-40 AD)  is also recorded in the charters to the book of Kells as both laity (alumnus of Kells) and  as witness to the freedom of Kildalkey (land transfers to the church of Columcille by Conchubar Maelseachlain). His brother Maelan d.1050, was a lector in the monastic site of Ceanannus (Kells), dedicated to Columcille.

Lynan and his wife died in the east while they were returning from Rome. Successor as lord of the Gaileanga  recorded 1060AD in the annals would be his son Leochan mac maic Maolán.  

Sept and/or the territorial references of  Leochain/Lorkin were no longer used by monastic scribes from that point forward in annal entries for this specific lineage. All subsequent entires attached the verbal identifier of mic, maic and Mic Maoláin, verifying the collateral evolution based on marriage to royalty (Southern Ui Neill Clann Cholmain) of the surname and family of Mac Maoláin, tigherna Gaileang Breagh slain 1144AD.

Locales of the Gaileanga and Luighne of Mide and Brega during the dynastic era of Sil nAedo Slaine and Clann Cholmain (Mael Seachlain kings of Mide and Tara (Brega) are illustrated on the map below.
