I can't believe that I'm the first Fitzer to post here!C'mon people!!!
My Fitzer clan springs from Northern Illinois.We're all descended from my great-grandfather, John Fitzer (originally Theodor Johann Friedrich Fitzer), born in 1860 and emigrated to USA in 1873 from Passow, Germany.
Most Fitzers from this group were born in either Joliet, New Lenox, or Frankfort Illinois.
Drop me a note some time. I've got a lot of data but I'm still searching.
