My Great Grandfather, Jacob Kaska, came from the Soca region of Slovenia with his Brother Filipp. Something happened to Filipp though as the only record we have of him is his immigration to this country. Then, somewhere along the line, My Great Grandfather started using the name Filip and left the country to go back to Slovenia for a while then came back as Phillip...but hen called him Jacob. I am trying to find out whether he was Filipp or Jacob and what happened to the other one...it's my only real family mystery.
