I think Herman Decker was my husband's great-great grandfather. The only thing that I have on Frank & Elizabeth is that they both were born and reared in Oldenburg, Germany. They came to the United States in 1842, and located in Cinncinnati, Ohio, where they both died nine years later. I am going to see if my husband's 3rd cousin has any more information about the decker family. His mother is a Decker.
