Mac Maoláin is an ancient surname of native Irish origin, which evolved from the earliest root forename of Maelán and the later variant forms Maoláin; and Meallain. It would eventually become anglicized as: MacMullan, MacMullen, MacMoylan, McMullan, McMullen and McMullin.
The existence of early Irish variants Mac Maoláin, Mic Maoláin, Mhic Mhaoláin and Mec Maoilin, are verified by: ancient Irish townlands established in the locales these families inhabited and, by diversified Irish Annal entries spanning several centuries plus specific hand written notes found in the charters section of the "Book of Kells".
These forenames Maelán, Maolán, Maoláin, Meallain and collateral surname Mac Maoláin (the son of), connect in terms of historic pathway information to some of the earliest irish tribal clusters identified in ancient texts, i.e: the Fir Gallion; the Ui Bairrche; the mercenary families clustered with Clanna Rory (Laighsi), the Laigin dynasty of Leinster: the Ui Failghe; the Ui Dunlaigne; and Clan Donnchada.
These territorial dynasties emerged over periods in excess of several thousand years, with diverse variants of Maelan recorded in several different locations by unrelated families. During the 10th century these forenames would evolve to surnames.
As a collateral surname, Mac Maoláin 1st emerged historically during the 11th century amongst families associated with the Mide (Meath) and Brega Gaileanga and Luighne.
Sequentially it is also be found recorded in various monastic sites such as Ceanannus (Kells), Clonmacnoise, Clones, Clonfert, Kilnamanagh Roscommon and Kilmactranny Sligo.
Monastic occupational records contributed to the more frequent use and eventual adoption of the tonsured form of Maolain (bald) vs the early irish original form of Maelan (hillock), making the variants Maolain (O'Mullan, O'Mullen) variants eventually the common form adopted in Ireland.
Ancient pedigree's posted for variant Connacht and Mide Gaileanga and Luighne septs indicate several different cultural and topographic relationships i.e: with the Eoghanachta, sons of Cian (Cormac Gaileang), with Dal Riada Clanna Rory (Fergus Gaileang) and with the sons of Cathoir Mor Ui Failge (Sil Cormaic Gaileang).
Where these tribal references appear, they very often include comments by historians regarding mythologic connections of these groups to Lugh, Nauda and the mystic Tauth De Dannan.
Specific families (clearly there was more than one) identified in more recent published works include: Irish Genealogical Society's published history of Clanna-Rory, with MacMullen noted on page 16 and Fergus Gaileanga on page 86: plus a research project titled "Ethnology of the Gael" by C. Thomas Cairney, listing O'Mullan on pages 78, 82 and 87
Ancient pedigrees extracted from the "Book of Glendalough" and "Book of Leinster", leading sequentially from the form Maelan, to the more frequently used monastic variant form Maoláin and collateral family Mac Maoláin, recorded in the ancient Irish Annals as Lords (Tiarna or Tigernach) of the tribes of Luighne Midhe, Gaileanga Mora and Gaileanga Brega, inhabiting locales in Upper and Lower Kells Meath, Castlerahan Cavan, Clankee Cavan, Skreen, Dunboyne and Castleknock Meath.
Warrior elements of these Gaileanga (Gallen) and Luighne (Lune) families are said to have been driven during the Norman invasion across the Shannon into the territory of Concannon Ui Diarmada (Corca Mogh in Galway and Roscommon) where they were later appear recorded as the sept O'Mullen along with the affiliated family O'Lohan.
In Roscommon monastic descendants are identified in the parish of Kilnamanagh (home of the monks), townland Cluain Mhic Mhaolain (=meadow of McMullan) plus diocese of Elphin and Loch Ce.
Monastic descendants who adopted the surname Mac Maoláin were employed as: erenaghs and clerics in the early Celtic church of Morgallion, diocese of Kilmore, territory of O'Reilly; plus Cluain Mhic Mhaolain diocese of Elphin in Roscommon, territory of Mac Dermot; and in Baille Mac Maolain (Bally Mc.Mullen) Abbyleix Laois, territory of O'Mhorda (O'More).
McMullens are also recorded in more recent times as Clerics and Bishops of the primate diocese of Armagh, employed in the suffragan dioceses of: Kilmore; Meath; plus, Connor and Down of Ulster, where MacMullen held the bishops seat in Cabra Iveagh (territory of Magennis).
Anglicized forenames flowing from these ancient pedigree families right up to the medieval period, are still be found today in descendant Mullen and McMullen families. They include: Aengusa (Angus, Aeneas or Eaneas), Aodh (Hugh), Artuir (Arthur), Donnghal (Donal, Daniel), Dunacan or Donchada (Donagh, Duncan, Dennis), Cathal mac Donchada (Charles), Laidgneain, Laidcnen (Lynan), Morda (Moore), Seamus (James), Sean (John), Seargus (George), Robhartach (Robert) and Tomias or Tomealtach (Thomas).
Prominant forenames such as Thomas, James, John, George and the occasional Andrew emerged after the Norman Invasion. Adopted from new monastic foundations such as the Priory of St John in Kells Co. Meath, the Priory of St James in Cruisetown Meath, plus Knights Hospitaller's of St Johns erected in Kilmainhamwood Meath and Kilough Co. Down, these forenames came from Brittany Saitns revered by the "Landed Gentry", specifically landowners of Norman extraction (Thomas, Cruise, Butler).
The forename Charles is found in the pedigree of O`Reilly who became lord of Machaire Gaileang (Morgallion) on the fall of Mac Maolain (Charles O`Reilly d.1196). Both these surname families (Reilly/McMullen) were connected to the monastic sites of Ceanannas (Kells= Conchubar Mac Maolin Bishop) and of Loch Oughter in Co. Cavan, founded by Carlus Mac Mailin (likely variant form of Charles McMullen).
11th century descendants of Maelan (a lector) and Laidcnen Mac Maolain (laity & lord of the Luigne Meath) functioned in these monastic enclaves as erenagh=stewards of termon church lands, monastic builders and lay clerics.
The last Irish Chieftain connected to the Gaileanga pedigree and recorded by his surname in the Irish Annals (Lord of the Gaileanga Brega (Duleek/Dunboyne area), was Mac Mic Maolain, slain in 1144 AD. One additional reference to a Lord of the Gailenga is recorded in …...without surname clarification.
Some monastic Mac Maolain's appear to have been driven along with the princes of Brega, Dunn (Regan-descended from the family O'Duinn) into Co Laois where a townland of Bally Mc.Mullen suggests their presence and probable status as erenaghs (airchinneach) to the dominant family O'More in the monastery of Abbyleix.
This property referenced as Ballymullen alias Mc.Mullen, was confiscated in the later part of the 16th century and reallocated in Irish statutes dated 1639.
Many different pedigrees and locations have been posted linked to this surname or the history surrounding it. They verify as genetic studies have, that several distinct and separate families bore this surname.
Most modern historians note these ancient pedigrees conceptually should be read with a view of likely only being completely reliable from about the 9th century onward, as the constant shift in dynastic affiliations of earlier times produced many assigned or corrupted versions.
Below are listed all the possible pedigrees which might connect back on Irish evolutionary pathways to a family whose dominant male forename may have formed the root variant which evolved to a an identified grouping his Mullen ancestor may have been part of:

Heraldic and historic pedigree information collected from documents produced over several thousand years, identify sequential clusters that possibly generated a downstream surname of Mullen & McMullen:
Ui Maeláin (Ui Bairrch) Dal Niad Chuirp
This very early line given as descendants of Eochu Guinech and Daire Barriaig, grandson of Cathair Mor, settled initially in the Kells Plain and Barony of Slievemargy Co. Laois under Ui Cellaig (Kelley). They are identified as a branch of Cineal Dal Niad Cuirp a cluster which historians suggest based on later pedigrees, link to the Luighne families who migrated both to Connacht and Midhe. Clanna Rory historical information suggests their clan cluster referenced as the Loighis also joined this dynastic group as militia (mercenaries), migrating from Uladh to the Laois area circa 300AD. One of these topographically clustered families is identified as Ui Maeláin, a family who likely generated the modern surname variants of Moylan, Mullen, Mullan, Mullins, Mullens, McMullan, McMullin and McMullen for this line.
O' Maoláin (Ui Maine) Ui Díarmada
The territorial group of Ui Diarmada, identified as 1st located in the Sil Anchia area of Loughrea Galway, settled much later in the baronies of Killian and Ballymoe (Corco Mogh). O'Mullen, a sept transcribed with modern variants of Mullin, Mullan and McMullen, were recorded here circa 14th century, tributary at that time to the Ui Maine (O'Kelly, but not found in the Kelly historic list of families ?). Mentions of the surname associated with Mac Dermott in Roscommon and later Sligo plus historic analyis suggests the possibility this family might have originated earlier in Cavan and Meath, driven across the Shannon during the Norman Invasion, settling here under a Chieftain named Concannon along with their affiliated Gaileanga Mor kin O'Lohan.
O'Mealláin (Ui Neill) Clan Fergusa
This line historically located in Dungannon Co. Tyrone under a hereditary chieftain O'Hagan, included sept variants such as O'Quinn (Cuinn) Mulfoyle, O'Mallon, Mellan and Millan, some of which were later transcribed as Mullen and McMullen, but also McMellon and the Irish McMillan. They are said to have been the keepers of St Patricks Bell, later holding significant churchlands in the county of Armagh and tributary in later times to the Northern Ui Neill.
O'Maoláin (Mullan) Clan Conchobhiar Magh Ith
This line suggested also to be of Ui Neill origin, included septs with surname variants of O'Kane, MacCluskey Mullen, Mullin and O'Mullan. Their hereditary overlord O'Cathain (O'Kane), were Lords of Creeve in Coleraine and Keenaght (now Londonderry), where a Mullan sept with a recognized chieftain was recorded as late as the 17th century.
O'Mellon (Sil Aedha Eaniagh) O'Murphy
This somewhat obscure family recorded with variants of Malin and O'Mellon, some of whom were later transcribed as McMalin, McMellon and McMullen, were located in the barony of Strabane Co. Tyrone under a Chieftain O'Murphy (Murchada, a chiefly surname more synonomous with the earlier Laigin dynastic families of Leinster). Historians to date have identified no ancient cineal, branch pedigree or conclusive lineage for this family. It is possible they either adopted or were assighned the false pedigree of Niall. The family might actually be related to either Mallon Clan Fergusa or the O'Mellon's sept of Clonmellon Westmeath (Southern Ui Neill), mentioned in )'Dubhagain's topographical poem of ancient tribes and septs created in the 14th century.
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 in different annals/locations as either the son of Maolán and grandson of Eccnigh Ui Leochain (Lohan) or Ui Lorcan (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) was also recorded in the charters to the book of Kells as both laity (alumnus of Kells) and witness to the freedom of Kildalkey (land transfers to the church of Columcille by Conchubar). His brother Maelan d.1050, was a lector in the monastic centre of Ceanannus (Kells).
Lynan and his wife died in the east while they were returning from Rome. His successor as lord of the Gaileanga recorded 1060AD would be his son Leochan mac maic Maolán.
Sept and/or the territorial reference of ui Leochain (Lohan) was no longer used by monastic scribes from that point forward in any Irish Annal for this specific lineage. All subsequent entires attached the verbal identifier of mic, maic and Mic Maoláin, verifying the collateral evolution based on this marriage to royalty (Southern Ui Neill) 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 Mael Seachlain Kings of Mide and Tara (Brega) are illustrated on the map below.
