I’m familiar with the Carrolls of Carollton, Maryland, Salvation. I’ve got a Carroll from MD in my paternal line. No evidence of his ever having been Catholic, but the question of some connection hasn’t been resolved and may never be, burned counties and all that.
Happy genealology searching.
My family had a book made with the Irish immigrant name. Then I met a fellow with the same name — loaned him the book, but none of his relatives are in it.
Must have been two or more of them that came over from Ireland. LOL!
