May surname: questions
What does the surname May mean in Irish?
Woulfe prints May under four entries. Mac Máighe is 'son of May' (short for Maheu, i.e. Matthew); Mac Máigheóc is 'son of Mayoc' or 'Mayog', a diminutive of Maheu; Máighiú is 'son of Maheu', a Norman form of Matthew; Ó Miadhaigh is 'descendant of Miadhach' (honourable).[1][2][3][4]
Is May an Irish or a Norman name in Ireland?
Woulfe calls Maheu 'the Norman-French form of Matthew' and says the Condon branch in East Cork and Waterford took the patronymic Mac Máigheóc. He also lists May under Ó Miadhaigh, which he calls an old Westmeath surname. His entries do not say which of these a given May family descends from.[2][3][4]
Where in Ireland was the May name found?
Matheson's 1890 birth index names Sligo as where May was principally found. Woulfe places Ó Miadhaigh in Westmeath, with the name now found in Roscommon and the southern parts of Mayo, and the Condon branch in East Cork and Waterford.[5][2][4]
Who cut off the head of Sir Hugh de Lacy?
Woulfe writes that it was an Ó Miadhaigh, 'by cutting off his head with a blow of an axe at the castle of Durrow in 1186'.[4]
