My husband is descended from the Johann Wurzbacher family of Baltimore City and Baltimore County. Our Johann E Wurzbacher was born in 1825 in Selbitz, Oberfranken, Bavaria. He had a son named Johann Ehrhardt Wurzbacher born 1853 - nothing else known about him. I don't know if this could be your John, but in any case, you might check out Selbitz. I believe Wurzbachers still farm in that area. Elenora Green
