Hi, i'm quite new to this. Someone thought that Wine meant friend but I do like to check. The other names you list ending in win, i would not just assume that they shared the same root as Wine and therefor would not have searched for this variant name. There again, i must admit i did not think of win to search for anyway. I guess things like that you pick up over the course of time?
How long have you been into name origins? thanks
Bobby
