I searched some online parish registers and found a baptism for Willm Lovely of Backlane in Dublin - parish St Audoen - on 7 Nov 1737, father Robt, mother Ruth. They were Church of Ireland (Protestant). I also have Lovely's in my tree, my ggrandmother was a Lovely, I am trying to trace her ancestors. If I get back as far as the 1700s and find any William's I'll let you know. Good luck in your search, Irish records are quite sparse, but if I can be of any other help let me know.
