I have heard of a Sussanna Doberstein (b. 8 Nov 1834 Germany) who married a Michael Labode (b. 6 Jan 1832 Posen/Germany) in 1864.Both lived in Rush City until 1915 and 1908, respectively.
I am related via a Wilhelmine Doberstein (b. 2 Jun 1855 Germany) who was married three times (Wachholz/Persank/Danner).Although she lived primarily in Dakota County, MN, she also can be found living in the Rush City area after the death of here third husband.
I have 25 Dobersteins in my records, but I am having trouble trying to relate them all to a single common ancestor pair.
My earliest ancestors are Ferdinand Doberstein (father of Albert) and Adam Doberstein and Maria Darne (parents of Wilhelmina).
