FILSAK / FILSAC; anywhere; anytime I'm studying the FILSAK / FILSAC family worldwide. It's very very very rare surname. I've traced my own line to villages in South of Czech Republic. I have information on branches of the family in CZ, A, D, UK, F, USA, CA. Interested in contacting any other members of the family to share information. http://mujweb.cz/www/jardaf [email protected] (Jarda Filsak)
