I'm excited that Genforum is hosting this new site about the Leipzig surname, which is relatively rare in this country (USA).
I've been researching my husband's family (Victor Leipzig) and will post info here over the next few weeks hoping to make some connections.
Not all Leipzigs in the US are related. Some came from Prussia. They are more likely to be named Leipziger, meaning someone from Leipzig. My husband's family came from Wincheringen, Germany, which I believe is in the south near the Rhine.
About 2/3 of the Leipzigs in the US are Catholic, about 1/3 are Jewish. Presumably the surname originated in the town of Leipzig in Germany. I believe that there are members of German nobility with the Leipzig surname, but I have not been able to trace this.
My husband's Leipzig family was originally from Stadwerne/Stadwernen. Heinrich's son Peter moved to Wincheringen. There are no more descendants with the Leipzig surname in Wincheringen (although there may still be descendants in the female lines), but I believe there are still Leipzigs in Stadwernen.
Heinrich Leipzig, born in Germany about 1800, married Elizabeth Distel BEF 1823. Elizabeth was born ABT 1785/1800. In 1823, they had my husband's ggreatgrandfather, Peter Leipzig ( b. 1823 in Stadwernen, died Dec. 19, 1902 in Wincheringen, Germany). They undoubtedly had other children, but I have not yet examined records in Stadwerne.
In the 1840s, Peter moved to Wincheringen to teach school. He married Eva Wolf on January 31, 1849 and they had 9 children.
We have examined the microfilmed church records from the Catholic Church in Wincheringen to gather our information on Peter and Eva's children, and Victor's father and sister have traveled to Germany to personally view the records.
All five of Peter Leipzig's sons, Peter (b. April 11, 1854), Theodor (b. June 17, 1858), Matthias [the one who survived] (b. Feb. 24, 1860), Phillip H. (b. Jan. 12, 1862) and Francis (b. Sept. 16, 1864) emigrated to America at separate times and I will post info on them in separate messages. We have info on the descendants of Francis Leipzig that is current. I have some info on the first and sometimes second generation descendants of the other brothers. If you think this might be your family, we'd love to hear from you.
Peter and Eva's first two children, Barbara and Matthias, died as children.
Peter and Eva's daughter Susannah. (b. May 10, 1851) married Matthias Hengen in 1874 and had 9 children: Maria, Peter, Anna Maria, Susanna, Anna Magdalena, Anna Agnus, Anna, and Catharina. They seem to have remained in Wincheringen.
I'll post info on the five Leipzig brothers who immigrated to the Chicago / Wisconsin / northern Indiana area later.
