I'm looking for any information on my Great Great Grandfather Samuel Conrad. I know he died in Illinois, and I know he was married to Mary Ann Ishler. His children were Edwin Conrad, Perl Ellis Conrad, and Harry S. Conrad (my line). I have found his burial/tombstone and the dates are hard to see, but I believe he was born in 1838, and passed in 1911. Any information about him would be greatly appreciated! Especially his parents names!
