It would be great to hear more about it and your surnames from you on this board. I think the Sephardim of this area aren't as well known for the western world as clear as they could be regarding surnames, migrations, customs, etc. I hope you get many more responses. Immediately, off the top of my head, do you know about JewishGen's site in the "Rom" area? Here's a link to a bit more info from JewishGen at http://www.jewishgen.org/ROMSIG/index.html
. Don't leave here though. I'm glad you've brought this up here!
