I don't have a particular special interest, although the way common names change between European languages has always been an interest. I'm an archaeologist and I did some linguistics at university as well, so I'm kind of interested in everything about the past, name history included.
Otherwise I'm just a basic "names nerd"! Lol. I post on the Facts board a lot because I have good research skills so if I've got time I can usually find information for people if it exists on the net.
