I'm looking for information on my great-great-grandmother, Catherine Rademacher. The only information I have is that she was born 15 Apr 1849 in Grothusemdan, Germany, and died 15 Feb 1925, Cortland, Gage County, Nebraska. She married Anton Oltmans, of Essens, Germany. I have no other information about the Rademachers in Nebraska or earlier in Germany. Though I remember meeting some at a Wagner family reunion in Lincoln Nebraska in the 1970s when I was young.
Any information will be greatly appreciated and I'd be happy to share what I know of Catherine. I can also be emailed directly at firstname.lastname@example.org.
