What location is your Florence? I have a Flore(a)nce McCarthy married to Susan (unknown last name - possibly Brennan. My Florence's father was Denis McCart(h)y and mother was Margaret (Tobin). They lived in the Appleton/Kaukauna area of Wisconsin. I don't have much on Fleur - what he did or any children but if you think this is a connection I'd be happy to share. I've been told that the male use of Florence was only in one line of the McCarthy's so I'm very curious about your info.
