According to naturalization request papers, Scott Co. IA, my g'gpa Heinrich Joseph Hennings is from Holstein. His birthday is circa Nov. 1839. According to census, he arrived in US in 1870. His brother, Hans Jacob, is listed in his naturalization request papers as from Dithmarschen. It's been said the two came together. Looking thru Germans to American, 1870, the only listiing is for H and H Henningsen, apr. 21 on the Silesicia (Hamburg Line). No other records show any further data regarding town or burrough they were from. My g'gpa settled in Crawford Co. IA. I'm now at a lost as to how and where to proceed.
Thankyou for any help.
