Origins of the surname "Mac Maoláin"

Artist: Michael David McMullen 

Mac Maoláin

Mac Maoláin as a surname evolved from the old Irish Gaelic root form "Maelan", a forename in use circa  700-900 AD.

Later middle Irish variant forms of Maoláin; Mailin; Maellain came into use circa 900-1200AD.

All of these variants are verified in numerous Irish "annals", with entries spanning hundreds of years.

A less certain possibility predating the written monastic entries, is found in translation of an Ogham narrative cut into the Aghascrebagh Standing Stone found in Co,  Tyrone.

One of the very few Ogham stones in the north of Ireland, it was almost certainly a standing stone before the Ogham script was cut into it.

Standing 1.2 metres high, the stone itself appears to be from about 500AD, the much worn inscription interpreted as Dottetto Maqi Maglani.

MAQI according to ogham experts analyzing this stone, was an earliest form of Mac=son of, leaving some convinced this might be referencing an individual who was a son of Maelan


These "original forename variants" eventually became anglicized in the modern era as the surnames Mullan/Mullen/Mullin and "son of"= MacMullan, MacMullen, MacMullin and MacMoylan.

Later they were shortened to the more common variants in use of McMullan, McMullen, McMullin and McMoylan.

Existence of the early Irish variant forms of Mac Maoláin, Mic Maoláin, Mhic Mhaoláin, Mec Mellain and Mec Maoilin, can be verified in:

1.Ancient Irish townland's established in the locales these families inhabited;

2. Diversified Irish annal entries recorded by scribes located in different areas and spanning several centuries;

3. Specific hand written notes found in the charter section of the "Book of Kells"; and

4. Recorded surname's of individuals identified in ecclesiastic histories for several Irish dioceses.

These diverse resources highlight the factual reality, that several unrelated families adopted this forename as their familie (clan) surname in Ireland.

More importantly the diversity exposes the simplistic research efforts adopted by consumer crest marketing companies, who cobble together questionable analysis about a specific surname and where it first emerged (based on who they are marketing). These outdated descriptions remain static, ignoring the vast amounts of modern updated database research input even when that information is provided to them as evidence.

The chiefly forenames Maelán, Maolán, Maoláin, Meallain and collateral medieval surname of Mac Maoláin (son of), surface in terms of historic identification, in some of the very earliest locational listings of affiliated populations and dynastic tribal clusters identified in Irish historical research.

Extracts from these ancient texts, with references to a significant chieftain, and the later use of his forename to identify a family grouping can be found sequentially:

* In the early chiefly families of Ui Bairrche which included their mercenary allies the fianna of  Clanna Rory (the Laighsi);

* In the downstream dynastic families of the Laigin (pronounced Lein/Lyne) i.e, the Ui Failghe; Ui Dunlaigne; Ui Fergusa, and Clan Donnchada; plus

*In the genelach (pedigree) of the Luighne/Gaileanga alliance of Mide and Brega (modern counties of Westmeath and Meath).

Territorial dynasties emerging over periods in excess of several thousand years, were constantly reshaped by conquest and defeat. This would produce several diverse variants of the original forename Maelan, recorded in different locations, for clearly unrelated families (clan/sept)

The forename is also found in diverse monastic sites such as Ceanannus (Meath), Clonmacnoise (Offaly), Clones (Monaghan), Swords (Dublin) Clonfert (Galway), Kilnamanagh (Roscommon), Kilmactranny (Sligo), Daire (Derry columcille), Downpatrick (Down) and Ahoghill Kilconway (Antrim).

It was monastic occupational records and the variant form selected by scribes for individuals recorded in them, which contributed to the later more frequent transcribed selection of the tonsured form (Maolain= bald) versus original Maelan (=of the hillock or height) to identify individuals of this forename.

Tracking ancient pedigree's and territorial population groups where a prominent individual named Maelan & Mc surfaced,  will confirm as mentioned, that several different cultural and topographic tribal clusters and tributary relationships are linked to it.

Where tribal references appear in ancient historic renderings, they often include mention of ancient pagan dieties, such as Lugh, Nauda and the mystic Tauth De Dannan. 

Specific surname families identified in more recently published genealogical and antiquarian research works include:

Irish Genealogical Society's history of Clanna-Rory, identifying the seat of MacMullen on page 16 and the migration of Fergus Gaileang to "Teffia" (modern day Westmeath) on page 86;

Ethnology of the Gael  project by  C. Thomas Cairney, listing  O'Mullan on pages 78, 82 and 87, with a suggested descent from the earlier families of Cahair Mor and the Laigin.

O'Hart "Irish Pedigrees" (Origin and Stem of the Irish Nation) with a  suggested descent from a Connor brother of Dathi (#102 on the Concannon pedigree), his son Donall, his son Maolan, and also suggestive of earlier Laigin origins.

 O’Growney, in his monastic research provides examples of sites connected to early ecclesiastic tradition and use of the forename variant Maelán (Daire Maelain Fermanagh, Cell Maelain Limerick and Killmoylan Galway).

Widely dispersed ecclesiatic sites where a variant has emerged include several in county Laois, one of which may have been according to the O’Growney research conclusions, the very 1st to house a monastic given the forename of Maelan:


These different pedigrees and topographic suggestions verify as modern genetic studies have, that several separate families in different locales, adopted this chiefly forename as their surname over many centuries.

Most modern historians wisely caution that ancient pedigrees should be read with the view of topographic alliances versus agnatic descent (e.g. the Ui Bairche/Laighsi cluster) as chiefly families were tacked on to dynastic pedigree's to ensure participation in the Brehon competition for tigernach=king or territorial lord.

Generally antiquarians consider ancient pedigree's as only becoming completely reliable from about the 9th century onward, due to the constant shifts in the dynastic affiliations of earlier times.

Many families (clan/sept) now present a pedigree that was either assigned, or in some cases a false/corrupted version, but carried forward to modern times.

Below are listed ancient pedigrees found back on recorded Irish evolutionary pathways where a prominent male forename in that particular territorial cluster, might have later spawned a clan surname of Mullan, Mullen, McMullen. (note three of them suggest common descent from a Munster Ailella Auluimm)

Mac Maoláin

The 1st family recorded with the surname "Mac Maoláin" emerged in annalistic records of a ruling family, early 10th and 11th century.

They are identified as associated at that time with the Mide & Brega tribal clusters of Luighne and Gaileanga, and being tributary to the Ard Ri (High King) family of Mael Seachlain (Southern Ui Neill):


A map of the "Breifne Region"(circa  700AD) which predates the arrival of Ui Briuin O'Rourke and O'Reilly clans, illustrates the topographic locales occupied by Gaileanga Mora and Mide/Brega Luighne families (Castlerahan & Clankee Cavan; Lune Mide; Upper & Lower Kells, Fore & Morgallion Meath. (Map compliments of the Royal Society of Antiquaries of Ireland)

Notices are found in diverse Irish Annals relating to this family Maelan, Maoláin, Mic Maolain, identifying them as of the Gaileanga and Luighne, and identifying the tribal clusters they were aligned with.

In addition these sources verify their ecclesiastic links to the monastic site of Kells (Ceannanus) and "Alumnus of Columcille", during the period when Kells was the primacy (head of the monastic branch and sites in Ireland and Scotland).


Sequential annals, reveal their wider involvement with these tribal elements both in the conflicts of that era and the monastic communities. In short our ancestors were a warrior class but simular to all ruling families, also had relatives who were part of monastic orders.

Mac Maoláin (Gaileanga Mora and Brega) 

A Chieftain forename Lorcan or Leochain  (Larkin or Loughan, Logane, Lohan) circa 10th Century, is identified in the Irish Annals as the Lord of the Luighne/Gaileanga of Mide, Cavan and Brega.

1037AD, Laidcenn (variant Laidhgnen anglicised Lynan), is listed by scribes located in different monastic locations as the son of Maolán, and grandson of Eccnigh Ui Leochain (translates as Lohan)/Ui Lorcan (translates as Larkin).

Lynan became  the king of the Luighne/Gaileanga Mora in 1037AD. He married the daughter of the Gott  king of Uisneach=Westmeath Southern Ui Neill (the Gott was the son of  the Ard Ri Conchhubar Maelseachlain)

Lynan was recorded in the charters to the "Book of Kells"as both laity (alumnus of Kells) and  a witness to the freedom of Kildalkey (land transfers to the church of Columcille (circa 1025-40 AD) by Conchubar Maelseachlain.

Lynan was taken prisoner (hostage) in 1038 during conflicts between competing Mael Seachlain "derbfine" for position as Ard Ri  

His brother Maelan d.1050, was a lector in the monastic site of Ceanannus (Kells), dedicated to and at that time the primacy of the kin of Columcille.

Lynan and his wife died 1051, in the east returning from a  pilgramage to Rome. His son was elected successor as lord of the Gaileanga (but not of the Luighne) and is 1st recorded in 1060AD as:

 Leochan mac maic Maolán (Logan Mac Maolain).

Territorial references are no longer used by scribes from this point forward. Subsequent entries attach the verbal identifiers of mic, maic and Mic Maoláin, verifying the collateral evolution based on marriage to royalty (Southern Ui Neill (the Got) Clann Cholmain) of this surname and family of Mac Maoláin, tigherna Gaileang Breagh slain 1144AD.

Authors note: Locales of Mide and Brega during the dynastic era of Clann Cholmain and Sil nAedo Slaine (the Mael Seachlain kings of Mide and Tara (Brega) are illustrated on the map below. When reading the annals, this clarifies that the modern day county of Meath (Irish Mide) was then referenced as Brega, and Westmeath referenced as Mide (Meath).
