Someone on the Bavaria board said the surnames don't come from that area and seem to have come from Merzig, Saarland. This is the post I originally made below, help would still be appreciated:
I keep hitting a dead end here.
Looking for ancestors of Katherine Mary Tschanhenz (May 1871 - Nov 1952, born and died in Iowa). Her father is a Martin J. Tschanhenz born Nov 11th, 1819 in what I believe was the Kingdom of Bavaria at the time; he immigrated to Iowa and died there in 1901.
His wife was Katherina Blitsch apparently from Rhine Plantz born Dec 12, 1833. She also immigrated and died in Iowa. Her parents were Katherine Schorsow (there's some debate on this) born 1800 in ''Prussia'' or Germany and died in the same area. Her father was Nicholas L. Blitsch born in Prussia 1808 and I believe he may have immigrated as well when his wife died.
The Tschanhenz is quite hard, but I'm not getting anywhere with the Blitsch either. The Tschanhenz seemed to get their name butchered in America, one obit called it Jachanhenz but that is literally the only place I've seen it spelled that way. At times the couple would shorten it to Henz usually for space reasons (like their headstone).
Both Katherine Tschanhenz and Katherine Schorsow changed the spelling of their first names several times. At times they'd be Cath, Kath, Katie, Cathy, Katherine, Catherine, Katherina and Catherina.
Any help would be appreciated.
