Mac Maoláin as a surname evolved from the old Irish Gailic root form of Maelan circa 700-900 AD. to the later middle Irish Gaelic variant form of Maoláin; Mailin circa 900-1200AD
These origin variants became anglicized in the modern era as "son of Mullan/Mullen: MacMullan, MacMullen, MacMoylan, McMoylan, McMullan, McMullen and McMullin.
Existence of early Irish variants Mac Maoláin, Mic Maoláin, Mhic Mhaoláin and Mec Maoilin, are verified by: ancient Irish townland's established in locales these families inhabited; diversified Irish annal entries spanning several centuries; specific hand written notes of the charter section of the "Book of Kells"; and in the ecclesiastic history of specific diocese in several provinces of Ireland.
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 recorded tribal clusters identified by Irish historians.
Extracted from ancient texts, they include: the Fir Gallion; the Ui Bairrche and their mercenary allies first clustered with Clanna Rory (Laighsi), plus Laigin dynastic pedigrees for Leinster of Ui Failghe; Ui Dunlaigne; and Clan Donnchada.
These territorial dynasties emerged over periods in excess of several thousand years, producing diverse variant forms of the forename Maelan, which was recorded in several different locations for clearly unrelated families.
During the 10th century these forenames evolved to surnames, and for Maelan and Maolain Leinster, the collateral surname, Mac Maoláin emerged in records beginning 11th century for a family associated with the Mide (Meath) Luighne and Gaileanga tribal clusters.
It is also found recorded in diverse Irish monastic sites such as Ceanannus (Kells), Clonmacnoise (Offaly), Clones (Monaghan), Swords (Dublin) Clonfert, Kilnamanagh (Roscommon), Kilmactranny (Sligo) and Daire (Derry) Collumcille.
It was these monastic occupational records which contributed to more frequent adoption of the tonsured form (Maolain=bald) versus the original early form Maelan (=hillock). The variants Maolain (Mullan, Mullen) and Mac Maolain eventually became the most common form adopted in Ireland by dispersed regional scribes recording historic events.
Tracking ancient pedigree's and population groups that a prominent individual named Maelan & Mc were part of, suggests several different cultural and topographic relationships i.e:
the Eoghanachta, sons of Cian (Cormac Gaileang);
the Dal Riada Clanna Rory (Fergus Gaileang); and
the Laigin, Cathoir Mor Ui Failge (Sil Cormaic Gaileang).
Where these tribal references appear in historic renderings, they often include comments referencing mythologic connections with the dieties of Lugh, Nauda and mystic Tauth De Dannan.
Specific families (clearly more than one) that have been identified in more recently published genealogical works include:
Irish Genealogical Society's history of Clanna-Rory, MacMullen noted on page 16 and Fergus Gaileanga on page 86; and
"Ethnology of the Gael" a research project by C. Thomas Cairney, listing O'Mullan on pages 78, 82 and 87
Many different pedigrees and topographic suggestions have been posted linked to this surname and the history surrounding it. They verify as genetic studies have, that several distinct and separate families bore this surname over many centuries.
Most modern historians wisely caution that ancient pedigrees conceptually should be read with a view of likely only being completely reliable from about the 9th century onward, as constant shifts in dynastic affiliations of earlier times produced many assigned and some corrupted versions.
Below are listed all the possible pedigrees which may have connected back on Irish evolutionary pathways to a prominent family whose dominant male had a forename which evolved to a Mullan, Mullen, McMullen.

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.
