I am searching for more information on the Sittler family that settled in Wheaton, DuPage County, Illinois that may have branched out from there into other counties. My name now is Connie Tillotson. My grandfather Alber John Sittler is the son of Aloysious Sittler whose father is Oswald Sittler as far as I can determine. Oswald had a brother by the name of Martin and a sister by the name of Louise and a sister by the name of Philomena or other spelling.
