Thank you for your followup James! My delimma is finding Henry's exact birthdate and birthplace. You're correct. Prussia is quite broad! Since I speak german, and have lived over there, I'm betting his Prussian name was Johann Heinrich Miller (Moeller, Muller)? I'm wishing I could find some kind of a tie. His wives were both American as far as I can see, so to tie him to someone on LDS websites requires a parent's name or a spouses name to be sure it's him. His age makes me think he could have had a wife in Germany area who could have died before he came to the U.S. This was common. But maybe he did wed first in the U.S. Thanks for all of your help! I will continue to search.
