M. Ressler Genealogical Database

I have fairly confidently linked Georg and Anna to my known ancestor Isaac. There are now enough clues that a connection seems likely, though I still can't absolutely prove it. The 1860 census lists a Daniel Ressler and his wife immediately below Isaac Ressler and his family implying that they were immediate neighbors. This also makes it very likely that they were related, probably brothers as hinted by various online sources. Fragements from some of those sources are in attached notes.
