Wow!!!! Is all I can say. This my first time visiting this site and I had no idea that there are so many Seys' all over the world. In response to Seys' from Belgium, most definately our roots are from there. My grandfather came to Canada from there. To my knowledge he also came here with his brothers to farm land in Ontario. I would love to speak with any of you. I believe there was a lady in my family (great great aunt) who stayedin Belgium and some relatives that moved to France.
