Brothers Jacob (b. abt 1800) and John (b. abt 1805) emigrated from Pennsylvania to Wayne County, Ohio, before 1850, and Jacob died there. John moved to Adams County, Indiana, and then Buchanan County, Iowa, where he died. I'm searching for the parents of Jacob and John, probably from Pennsylvania. Graciously, in September 2016 Marci King searched Amish and Amish Mennonite genealogies by Hugh F. Gingerich and Rachel W. Kreider and found no evidence of these Millers. Thus, these Millers most likely were not Amish or Mennonite.
