I don't actually have any of those people in my family, but it was a little strange to see two surnames that I have in my family who also married. My great great grandfather was Conrad LUX who was born in Germany, possibly Rhine Province, Germany, who married a Gertrude KAYMER/KAUMER on April 18, 1845
Thier son Carl Matthew Lux was born Feb 6, 1852 in the Rhine Province, Germany Carl later came to America in 1883 and ended up in NEBRASKA and married Regina Feller/Fuller
It seems strange that I have Lux's, Kaymer's, and Nebraska in common with you. I also have the dates similar in the birth years and the places in Germany. I wonder if there is any connection?
