Kinsella surname: questions
What does the surname Kinsella mean?
Woulfe gives Kinsella as a form of Cinnsealach, 'belonging to Ui Cinnsealaigh, in Wexford'. The rarer form Ó Cinnsealaigh means 'descendant of Cinnsealach'.[1][2]
Where in Ireland is the Kinsella name from?
Co. Wexford, according to Woulfe. In 1890 Kinsella births (81 entries including spelling varieties, 75 spelled Kinsella) were principally found in Dublin, Wexford, Wicklow and Kildare; 73 of the 81 entries were in Leinster.[1][4][6]
Are the Kinsellas related to the Kavanaghs?
Woulfe says both families descend from sons of Diarmaid Mac Murchadha, King of Leinster: the Kinsellas from Enna Cinnsealach and the Kavanaghs from Domhnall Caomhanach. He says Cinnsealach was, like Caomhánach, an agnomen which supplanted the real surname.[1][3]
Is Kinsellagh the same name as Kinsella?
Matheson (1901) lists Kinsellagh among the varieties of Kinsella, and O'Donovan's translation of the Four Masters uses 'Kinsellaghs' under 1580.[5][7]
