Mac Maoláin is an ancient surname of native Irish origin evolving from earlier root forenames of: Maelán; Maoláin; and Meallain. It would later become anglicized as: MacMullan, MacMullen, MacMoylan, McMullan, McMullen and McMullin.
The existence of the early Irish variants Mac Maoláin, Mic Maoláin, Mhic Mhaoláin and Mec Maoilin, are verified by the existence of Irish townlands in locales these families inhabited, numerous Irish Annal entries spanning several centuries and specific written notes found in the charters to the Book of Kells.
The forenames Maelán, Maolán, Maoláin, Meallain and collateral surname Mac Maoláin (the son of), connect in terms of historic pathways to some very early population clusters in Ireland identified as affiliated with: Fir Gallion, the Ui Bairrche, mercenary families first clustered with Clanna Rory (the Laighsi), then later part of the Laigin dynasty of Leinster, the Ui Failghe, Ui Dunlaigne and Clan Donnchada.
These territorial dynasties emerged over periods in excess of a thousand years, with the variant Maelan found recorded as co-located families. During the 10th century these forenames evolved to surnames.
As a collateral surname, Mac Maoláin emerged 1st in the 11th century amongst families of the Mide and Brega Gaileanga and Luighne. Later it can be found recorded in monastic centres like Ceanannus (Kells), Clonmacnoise, Clones, Clonfert, Kilnamanagh Roscommon and Kilmactranny Sligo. Monastic occupational records contributed to use of the tonsured written form Maolain (bald), making it eventually one of the more common surnames found in Ireland.
Pedigree's posted for the Gaileanga and Luighne septs indicate a sequential cultural and topographic relationship first with the Eoghanachta, sons of Cian (Cormac Gaileang), then Clanna Rory (Fergus Gaileang) and then sons of Cathoir Mor Ui Failge (Sil Cormaic Gaileang) plus shared mythology references connecting with Lugh, Nauda and the mystic Tauth De Dannan.
These families are identified in Irish Genealogical Society's published history of Clanna-Rory, with MacMullen noted on page 16 and Fergus Gaileanga on page 86. Research titled "Ethnology of the Gael" by C. Thomas Cairney identifies O'Mullan on pages 78, 82 and 87. Pedigrees in the Books of Glendalough and of Leinster, lead sequentially from Maelan, to the alternate variant Maoláin then collateral Mac Maoláin, recorded in the ancient Irish Annals as Lords (Tiarna or Tigernach) of the tribes of Luighne Midhe, Gaileanga Mora and Gaileanga Brega, located in Morgallion Meath, 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 back across the Shannon to the territory of Concannon Ui Diarmada (Corca Mogh in Galway and Roscommon) where they appear recorded as sept O'Mullen along with the family O'Lohan. In Roscommon they are identified in the parish of Kilnamanagh (home of the monks), Cluain Mhic Mhaolain (=meadow of McMullan).
Monastic descendants who had adopted the surname Mac Maoláin were employed as erenaghs and clerics in the early Celtic Church of Morgallion, diocese of Kilmore, in 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 as Clerics and Bishops of the primate diocese of Armagh, operating in the suffragan dioceses of Kilmore, Meath plus Connor and Down in Ulster, where MacMullen held the bishops seat in Cabra Iveagh territory of Magennis.
Anglicized forenames flowing from these very early pedigrees and the medevial period are still found today in related 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 (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 an occasional Andrew surfaced primarily after the Norman Invasion, emerging both from new monastic orders such as the Priory of St John in Kells Co. Meath, Priory of St James in Cruisetown Meath plus the Knights Hospitaller of St Johns in Kilmainhamwood Meath and Kilough Co. Down. These names were inherited from the Landed Gentry, specifically those landowners of Norman extraction (Thomas, Cruise, Butler) and the Saints they revered.
The forename Charles may have emerged from the pedigree of O`Reilly who became lord of Machaire Gaileang (Morgallion) on the fall of Mac Maolain (Charles O`Reilly d.1196), as both connect to the monastic site of Loch Oughter in Co. Cavan, founded by Mac Mailin (variant). Alternately it may be derived from Cathoir Mor, Catha Mogh, or Cathal mac Donnchada of the Gaileang, all forenames well back in the mists of time, connected to the pedigree of McMullen. It was also the anglicised rendering of the father of Rory O'More (Calvagh) landlord of church lands in Kilmainhamwood occupied by McMullen erenaghs.
Downstream descendants of Maelan (lector) and Laidcnen Mac Maolain (laity) functioned in these monastic enclaves as stewards of termon church lands, monastic builders and lay clerics. The last Irish Chieftain connected to this Gaileanga pedigree, recorded by his surname in the Irish Annals, as Lord of the Gaileanga Brega (Duleek area), Mac Mic Maolain, was slain in 1144 AD.
Some of these Mc's appear to have been driven along with the princes of Brega, Dunn (Regan-descended from the family O'Duinn) into Co Laois where the townland of Bally Mc.Mullen confirms their presence and likely status, as erenaghs to the dominant family O'More in the monastery of Abbyleix. This property was confiscated in the later part of the 16th century.
Many different pedigrees have been posted which could attach to this surname or history surrounding it. Most historians note that pedigrees conceptually should be read with a view of likely only being reliable from about the 9th century onward, as the constant shift in dynastic affiliations produced many corrupted versions.

As mentioned, Mullan, Mullen, Mullin, Moylan and the collateral surname McMullen evolved to become some of the more common surnames in Ireland. Heraldic and historic information gives the following septs as possibly having generated this surname of 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 were identified as a branch of Cineal Dal Niad Cuirp a cluster which included based on pedigrees the later Luighne, families who migrated to Connacht and Midhe. Clanna Rory historical information suggests that a cluster referenced as the Loighis joined this dynasty as militia (mercenaries), having migrating from Uladh to this area circa 300AD. One of these topographically clustered families was identified as Ui Maeláin, generating modern surname variants such as Moylan, Mullins, Mullens, McMullins and McMullen.
O' Maoláin (Ui Maine) Ui Díarmada
This territorial group Ui Diarmada, were identified as 1st located in the Sil Anchia area of Loughrea Galway, settling much later in the baronies of Killian and Ballymoe (Corco Mogh). O'Mullen, a sept transcribed with modern variants Mullin, Mullan and McMullen were recorded here circa 14th century tributary then to the Ui Maine (O'Kelly). Historic analyis suggests the possibility this family originated in Cavan and Meath, and were driven back across the Shannon during the Norman Invasion, settling here under a Chieftain named Concannon along with their Gaileanga kin O'Lohan.
O'Mealláin (Ui Naill) Clan Fergusa
This line was located historically in Dungannon Co. Tyrone under a hereditary chieftain O'Hagan, included sept variants such as O'Quinn, Mulfoyle, O'Mallon, Mellan and Millan, some of whom were later transcribed as Mullen and McMullen, but also McMellon and Irish McMillan. They are said to have been the keepers of St Patricks Bell, later holding significant churchlands in Armagh Ulster and tributary to the Northern Ui Neill.
O'Maoláin (Mullan) Clan Conchobhiar Magh Ith
This line suggested also to be of Ui Neill origin, included sept surname variants of Kane, MacCluskey Mullen, Mullin and O'Mullan. Their hereditary Chieftain was O'Cathain (O'Kane), Lord of Creeve in Coleraine and Keenaght (now Londonderry), where a Mullan sept and recognized chieftain were recorded as late as the 17th century.
O'Mellon (Sil Aedha Eaniagh) O'Murphy
This somewhat obscure line containing surname variants of Malin and O'Mellon, some later transcribed as McMalin, McMellon and McMullen, were located in the barony of Strabane Co. Tyrone under a Chieftain O'Murphy (Murchada), a surname more synonomous with the Laigin dynastic families of Leinster. There is no ancient cineal, branch pedigree or conclusive lineage evidence listed for this line, suggesting they either adopted or were possibly given a false pedigree from Niall. This family may actually have been related to either the Mallon Clan Fergusa or the O'Mellon's of Clonmellon Westmeath (Southern Ui Neill).
Mac Maoláin (Gaileanga Mora and Brega)
This line identified culturally as 1st extant in Munster as mythological sons of Cian (Cormac Gaileang), and alternately as Red Branch Knights of Clanna Rory (Fergus Gaileang), emerged in the Dunmore area of Magh Seola Galway, branching 7th century to a territory called Gaileanga Mora in Cavan and Meath. A Chieftain Leochain (Loughan, Logan, Lohan) circa 10th Century, is identified in the Irish Annals as territorial Lord of the Gaileanga in Mide, Cavan and Brega. 1037AD, Laidcenn (variant Laidhgnen anglicised Lynan), listed variantly as the son of Maolán son of Eccnigh Ui Leochain (Lohan) and Ui Lorcan (Larkin), became the king of the Gaileanga Mora. He married the daughter of the Gott (Malachi King of Uisneach=Westmeath) of the southern Ui Neill and travelled with her to Rome on a pilgramage. Lynan had earlier (circa 1025 AD) been recorded in the charters of the book of Kells as both laity (alumnus of Kells) and as witness to the freedom of Kildalkey (land transfers to the church by Malachi). His brother Maelan d.1050, was a lector in the monastic centre of Ceanannus (Kells). Lynan and his wife died in the east on their return from Rome. Successor as lord of the Gaileanga in 1060AD would be his son Leochan mac maic Maolán. No further references to Leochain (Lohan) territory will be made from this point forward in the Irish Annals for his specific lineage. All subsequent entires use verbal identifiers 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.
