Here's the 1835 census of Rosenort farm #14 so that you can see for yourself how logical my assumption was:
So I was very surprised when I found his obituary, and it said that he was born in Neuendorf, Khortitsa, South Russia. But the obituary was written by my great-uncle Abraham K. Siemens, and I have come to recognize him as an interested and careful genealogist, so I trusted his information. Here is a snippet from the obituary:
I have searched all the online records for Khortitsa, trying to find a connection, but I found no Siemens there who were related. I don't know where his mother, Gertruda Thiessen, comes from; so I searched for her in Khortitsa without success. I didn't know what else to try, but this has really bugged me for a long time. Why would a boy be born in Khortitsa when his parents and grandparents always lived in Molotschna and even had a farm there?
I still don't have the answer, but I noticed a new bit of information today. The online version of Grandma says that his aunt Helena Siemens #3759 was married in Einlage, Khortitsa, on 19 August 1830, to Abraham Johann Friesen #3751. Since Mennonites were traditionally married in the home of the bride's parents, this would mean that little Gerhard's grandparents were living there in 1830. Did they live in Khortitsa from at least 1830 to 1834?
I've looked for Gerhard's parents and grandfather Siemens in Khortitsa without success, but what if it was his grandmother Katharina (Friesen) Siemens #46558 who had relatives in Khortitsa? What if they moved to Khortitsa to live with relatives when they retired from farming? They could have still been officially registered at their farm in Rosenort, Molotschna, but actually been living in Khortitsa. There are three Friesen families listed in the May 1814 census of Khortitsa, so I wonder if they might have been relatives of little Gerhard's grandmother Katharina (Friesen) Siemens. And one of them, Cornelius Friesen #198463 came from the same Heubuden church in West Prussia that Katharina Friesen came from. It's an avenue for further research.
