First found in Donegal, where they were anciently seated at Mullinashee. They
are descended from Cormac, son of Culenan, known as Cormac McCulenan, King and
Bishop of Munster who reigned for seven years in 905. Irish history, after the
Norman Conquest of England, was strongly influenced by the invasion of Strongbow
in 1172, almost equal to the enormous Irish cultural impact on England Scotland,
Wales and the whole of Europe before the Norman Conquest from the 1st to 7th
centuries. Many Irish clanns, sept names were intermixed and family groupings
became almost indistinguishable. This family name was found later in Cork
(Barryroe), Clare and east Munster.
Some of the first settlers of this family name or some of its variants were:
Lidean Quillane, who came to Maryland in 1667; Daniel Quillane, who settled in
Maryland in 1667; and Catharine Cullenan, who settled in Boston in 1849..
