Decendants of Johannes Schwartz of Switzerland

I have compiled some information about my maternal and paternal ancestors and also am in the process of adding my husband's maternal and paternal ancestors as well. The following are an alphebetical list of prominent family names: Bain, Eicher, Grove, Hennessee (Hennese), Miller, Schwartz, Simpson, Stauffer, and Wickey.

BAIN and Hennessee families are from Kentucky
SIMPSON family most likely from Tennessee (still looking for more accurate info on James Thomas Simpson b. Oct 24, 1904)
SCHWARTZ family from Berne, Switzerland and Berne, IN
STAUFFER family from Germany and Switzerland

I am always looking for more connections to these names. Feel free to contact me about these family names. Thank you.
