Where in Ireland is the McColgan name from?
Woulfe says the Mac Colgans were a sept of the Oirghialla, chiefs of Ui MacCarthainn in Co. Derry until dispossessed by the Cinel Eoghain, and afterwards erenaghs of Donaghmore, in Inishowen. In 1890 all 16 McColgan births in Ireland were in Ulster, principally in Donegal and Londonderry.[1][3]
Is McColgan the same name as Colgan?
Woulfe lists Colgan among the anglicised forms of Mac Colgan. He has a second entry, Ó Colgan, 'the name of an old family in Offaly, of the same stock as the O'Connors, O'Dempseys and O'Dunnes; also common in Thomond', whose forms also include Colgan, so not every Colgan belongs to the Derry sept. Woulfe cross-refers the two names: Mac Colgan 'more anciently Ó Colgan', Ó Colgan 'more anciently Mac Colgan'.[1][2]
Who was Father John Colgan?
A Franciscan of the Irish college at Louvain who published lives of the Irish saints: Acta Sanctorum Hiberniae (1645) and Trias Thaumaturga (1647). Woulfe says he was of the Mac Colgan family.[1][7][8]
