Dory, I believe your Dagenhart ancestor is the daughter of a post 1860 immigrant to NYC. 15 years ago I met a Dagenhart woman in Ohio near Canton. There are some Dagenhart brother in the pro Baseball hall of fame there. She told me her ancestors came to Ohio form NYC.
We have found Dagenharts in Many US states and in several parts of Germany. There is a large Family in BaVari,what Used To be Prussia and in Hessen where my ancestore was born.
My Cousin Cathy Dagenhart Baugh and I are writing a book on the dagenharts. I would love to see a copy of your old photo. We descend from Henrich Degenharts who was a Hessian soldier that deserted during the American Revolution.
Write Me , I think somwhere ther is an immigrant record of a post 1860 Dagenhart in NYC in my record files. My cousin Cathy may know who I am thinking of, She can be reached at Cdbaugh314@aol.com. I look forward to hearing from you Jerry L. Dagenhart 804-492-3699
