Piepho Family Genealogy Forum
I have the William Henry Piepho mentioned in the query on this page. There were also a good number of Piepho descendants who lived in Bremer Co., Iowa. You can check our Ted Cash's Web page at http://homepages.rootsweb.com/~cash/
This provides a good overview of, at least, my branch of the Piepho family.
Other than her name and that she married my great-great-grandfather I know nothing of Engle Dorothea (Bergmann) Piepho of Kolenfeld, Hannover, Germany,
