Robin, Here are the Ristau individuals that I have that I have not been able to link. I would like to learn of their common ancestors, if they are related:
Adolph Ristau (b. Mar 5, 1878 in Coal Valley, Rock Island County, IL)
Christian Ristau (b. Sept. 11, 1813)
Christina Luisa Ristau (b. Mar 14, 1791 in Koritowo, Schwetz, Graudenz, Westpreussen, Preussen)
Herman Ristau who married Anna Kuhn probably before 1893
Martha Ristau who married Charles Hanselman probably before 1911.
I too am happy to share if any of the descendants of these are of interest to you.Do you use any genealogy software? I can easily export my data in a GEDCOM format that any genealogy software can read.
By the way, here is a bonus question:I have an Emil Rahnke that married Louise Firch on Jun 12, 1903.Could I have this surname wrong?Could he be one of your Rahn's?
Any help you are willing to provide is greatly appreciated.
