I'm looking for any information anyone might have on the Sonnenberg and Manthei surnames, especially as how they relate to Osborne County, Kansas.
Both these families were German-Lutheran immigrants who are said
to have settled in the area of what is now Downs, KS around March
1870.
I'd appreciate any feedback or tips anyone might be able to provide.
There is a rough outline of the Sonnenberg line at http://members.aol.com/microfud/private/sonnenberg/sonnenberg.html
