Hi everyone. I know that my 4th-great-grandfather was named John Killian, born on December 7, 1809 in Pennsylvania, and died on November 14, 1896 in Lancaster, Pennsylvania. He had a wife named Hannah and about 6 children: Israel, Elizabeth, Mary Ann, Emanuel, Sarah, and John Edward (my 3rd-great-grandfather).
I've been stuck on John Killian for a while and cannot find anything about his parents/siblings. I believe he lived in Manheim, Pennsylvania at one point, and possibly New York. I also do not believe he is descended from "Andreas Killian."
If anyone knows anything, all help is appreciated! Thank you!

EDIT: It is unlikely that he lived in New York.
