My gr-grandfather was James Tunis. On his death certificate his bd was 1849 and bp Illinois. His birth parents were listed as James Tunis & Christina Dalton. I have checked on all of the census and I cannot find them. I have found a Jacob Tunis & Christina in Illinois but have no way of knowing if these are his parents or not. I have also found a James & Rebecca in Illinois with a son named James of about that same age but he was born in Ohio. I would appreciate any information.
