Two distinct origins, both Anglicised as Boyle. The Gaelic Ó Baoighill — descendant of Baoigheall ('vain pledge') — was a 10th-century Donegal kindred, the third great northern dynasty alongside the O'Donnells and O'Dohertys. Separately, the Anglo-Norman Boyles came to Ireland from Herefordshire in the late 16th century — Richard Boyle, 1st Earl of Cork (1566–1643), the great Munster planter. The two surnames are unrelated; the Donegal-Boyle and the Cork-Boyle pool are entirely distinct in their lineage and converged only in the modern English orthography.
The history of Boyle
The Ó Baoighill of Donegal were one of the three great kindreds of Tír Chonaill — alongside the Ó Domhnaill and the Ó Gallchobhair — and ran the Boylagh peninsula on the western Donegal coast as a sub-lordship of the O'Donnell kingdom from the 11th century to the Plantation. The barony of Boylagh, west of the Glenties, still bears the family name. Cardinal Tomás Ó Fiaich, in his 20th-century scholarship, identified the Boylagh Boyles as among the surviving Gaelic clan structures in continuous local possession into the modern era — unusually, given the comprehensive Plantation displacement of most Donegal Gaelic surnames.
Richard Boyle, 1st Earl of Cork — the 'Great Earl of Cork' — arrived in Munster in 1588 with twenty-seven pounds in his pocket and by his death in 1643 was the wealthiest man in Ireland, having acquired through the Munster Plantation an estate that ran to most of east Cork and west Waterford. His son Robert Boyle (1627–1691) was the founding figure of modern chemistry — Boyle's Law of gases, the founding of the Royal Society, the rejection of Aristotelian elemental theory. The Cork-Boyle line continues today as the Earls of Cork and Orrery, while the Donegal-Boyles remain heavily concentrated in the original Boylagh barony and across the wider Donegal-Sligo coast.
