" ... Came to America in 1853 and settled in Wisconsin. Married Mary Anne Garmshead (Germdheit, Gennsheid)
in Aug 1854. Moved to Peru Illinois around 1857 ..."
Regarding the original 2001 posting, there are few Wisconsin civil records that would have been generated for this couple 1853-1857 other than the Aug 1854 marriage (where was this recorded?), or a property purchase/sale.
Any births/deaths 1853-1857 would generally not be found in state or local level, but in church baptism or burial registers (some early births were recorded retroactively in the 1870s by families).
Milwaukee's German newspapers index has a handful of Büllesbach and Buellesbach entries, but none of them early enough to match this posting.
