In your posting you include this info on WILLIAM WADDELL HEIDELBERG, SR.: "served several terms as state Senator and Congressman."
I cannot find any Heidelberg listed in the Biographical Directory of Congress. The directory contains the names of all members of Congress since its beginning.
Did you mean that he served as a state senator and a state representative? Do you have the exact dates? He supported the Populists rather than the Democrats in the 1890s and I'm wondering how that affected him politically.
Also, I've not been able to find WILLIAM WADDELL HEIDELBERG, SR., in any census except 1910, two years before he died. Do you by any chance have a census citation for the earlier years? I particularly would like to find him 1870-1900.
