Hi! I am looking for information on these two surnames. My g-grandfather was Albert (Cizmar)Sismour married to Rose Shema of Ohio. They were married in the late 1800s. Their marriage certificate has Albert's last name as Cizmar. At some point he changed it to Sismour. I believe at the time of their marriage they were Catholic. However, I am trying determine if he or Rose are of Sephardic Jewish ancestry. Albert's father may have been Frank Cizmar. Rose's father was Wenzel or Wenceclaus Shema. Any leads or information would be greatly appreciated.
