About Seán Ó Maolalaidh

Lived 1419 – 1480 (aged 60–61).

Seán Ó Maolalaidh (fl. 1419–1480) was Chief of the Name.

Ó Maolalaidh of Máenmag The Ó Maolalaidhs (Lally, Mullally) were, with the Ó Nechtains (Naughton), one of the two leading septs of Máenmag in western Uí Maine. There is some evidence to suggest that they were not of the Uí Maine dynasty, but an indigenous people conquered by the latter in the 7th or 8th century.

Life A son of Melaghlin Ó Maolalaidh, Seán was to be the last Chief of the Name to live in the family's original homeland. Sometime after his election as chief in 1419, and by 1445, he, his clan and followers were expelled from the area by the Mac Hubert Burkes (Annals of Connacht - 1436.10 Seonacc son of Hugacc Burke died.)

Seán led the family to Tuam, where he leased eighteen townlands from Baron Athenry. One of the townlands was Tullaghnadalaigh (Tullynadaly), some four miles outside the town and thirty miles from Máenmaige.

Seán died in 1480, having been chief for sixty-one years, and was buried at Kilbannin. Tullynadaly was to remain the seat of the senior line of the family until their seizure in the 1690s. Many Mulallys and Lallys are still found in the Tuam area.

Notable descendants

Some of Seán's notable descendants included

Tomás Ó Maolalaidh, Bishop of Clonmacnoise (c.1509-1514) and Archbishop of Tuam (1514–1536) William O'Mullaly, Dean of Tuam (1558–1572) and Archbishop of Tuam (1572–1595) James Lally (died 1691) Gerard Lally (died 1737) Thomas Arthur, comte de Lally, baron de Tollendal (1702–1766) Trophime-Gérard, marquis de Lally-Tollendal (1751–1830)

Seán's brother was Conchobair Ó Maolalaidh who became successively Bishop of Clonfert (1447–1448), Emly (1448–1449) and Elphin (1449–1468). John Lally, inventor of the Lally column, was born at Kilbannon, Tuam, in 1859. Irish stage and screen actor Mick Lally (1945–2010) was a native of Toormakeady, north-west of Tuam.
