I see both you and Shelly posted your messages quite a while ago, but I wanted to contact you and say that I spell my last name Fillback, but a lot of my extended family spells their last name Fillbach. My family originates from Germany too. It is very similar to your spelling of Filback and Filbach. Could your family be connected to ours as well? I know I am related to a Donald Fillback from Missouri- I don't know if this is the same person you spoke about? In my family research I have come across your spelling, but just thought the missing "l" was an error in the record.
