I have begun researching by AHRENS family, and came across this 1999 post.
My gg-grandmother was Henrietta Louise AHRENS, dob 14 June 1855, dod 18 November 1925. She married Conrad TOEPFER, and they had 10 children, including my great-grandmother Louise Caroline TOEPFER, who married John Cleveland PETERSON. They lived in Boone, IA. I remember visiting my great-grandmother in Boone once when I was young.
Do any of these names connect with your AHRENS branch? Any information you may have will be most appreciated.
