John/Johann DIEHM + RIGHTMEYER - Wilhelm DIEHM - Berks Co. Penn.

Looking for information on the parents of John DIEHM possibly born: 13 July 1798 Berks Co. Pennsylvania certainly died: 25 June 1881 Illinois? Missouri?

and his wife Catherine RIGHTMEYER
born: 21 Jun 1800 died: April 1857

My limited sources for the parents of John DIEHM point to Wilhelm DIEHM b. 1 April 1760 d. Sep 14 1845 and wife Maria Catherine KLOOS/KLOHS b. 6 Nov 1763

Father of Wilhelm: (Johann) Peter DIEHM b. 1729 (some sites say Kembach-Wertheim, Germany, but there is a record of a Johann Peter Diehm being born the same year in Berks Co. Penn) d. 1793 Reading, Berks Co., Penn and wife Hanna Martha BOHN

Pennsylvania Church records and Abstracts of Berks County Wills seem to support this lineage, just looking for more proof. Also I have photo of John and Catherine Diehm/Deem. Willing to share information.
