uniquehorn , "Macateer. I've always liked that name since I found out it means "son of a nun"!
Macateer, McAteer, McAtee, or any other anglicised phonetic spelling such as McIntyre, is not based on a surname meaning 'son of a nun'.
It is from the surname Mac an t-Saoir. Son of a carpenter.
If you're keen on being the sprog of a religious of some sort; Taggart, MacTaggart etc are phonetic anglicisations of Mac an t-Sagairt. Son of a priest.
