My name is George Bisbee and am a descendent of the Friesenheim Hertensteins. I have a distant cousin that lives in Lahr (Modern-day city originally call Kippenheim). She has sent me information on my branch of the Hertensteins. One of the pages she sent me included the information on Johannes Hertenstein who married Katharina Elisabeth Wiber. The children listed were: 1. Johannes b.13 Jul 1769 d.28 Aug 1831; 2. Johann Georg b. 9 Oct 1772; 3. Johannes d. 10 Jun 1774; 4. Johannes b. 22 Jan 1776. I will ask this cousin to see if she can find information on the Wiber line if you are still seeking it.
Best was to communicate is my e-mail: firstname.lastname@example.org
