A Little Progress on the Millers/Müllers in New York
While I have not tracked them back to Germany yet, I have made progress on my father's father's father's family.
The Bixenman Family History book, by Sister Catherine Seemann had the most information so far found on the Mller family. It spoke of the Mller siblings, Charles (my great-grandfather), Gottlieb, Anna, Sophia, and Rika. It said Anna married a man with the last name of Quenzer and they were involved in a dry cleaning business in New York. It said Sophia married a man with the last name of Schmalzl and Rika married a man with the last name of Susenberger.
We have detailed information about the Charles Miller line since he is my great-grandfather.
The book said the siblings were all born in Germany and came to America. It said Charles was born in 1852, came to American in 1872 and lived in New York for a while before moving to Missouri where he met and married Philomena Bixenman. My father said that my grandfather said that my great-grandfather wouldn't talk about his history or family but that he came to America to escape service in the German military. He was afraid that if he talked about it, they'd track him down as a deserter. He said he thought he still had relatives in Germany but didn't know where.
This is all we knew about my great-grandfather's siblings. I have now found a bit more.
I found Gottlieb Mller in New York. He was born on May 29, 1868 and in about 1896 married a Rebeca (b. Aug 1867 in Germany). Their children (all born in New York) were Katrina (b. May 1897), Bertha Ann (b. Sep 1899) and Harold T. (b. 1905). Gottlieb owned a laundry cleaning business, apparently with his brother-in-law, whose last name was Quenzer. The business was called "Quenzer Bros and Mller", which later went out of business, and "Quenzer & Mller" at 1401 Madison Ave, New York was opened. His business partner for the second business was George Quenzer. This was in business from at least 1910 until 1919 for sure. He was not in this business in 1900 and the building that is there now was built in about 1920. A restaurant called "One Fish Two Fish" was at this location recently but is now closed and the building is vacant. They apparently opened a second location at 7th Ave and 168 Lenox Ave. In 1900, he was a brewer with a brewery wagon living at 116 E. 57th Street, New York. In 1910, he was a dry cleaning business owner living at about 1408 Madison Ave, New York. I'm not 100% of the address. His business was definitely at 1401 Madison Ave but the census has an entry four above his that specifies 1408 Madison Ave but nothing next to his or anyone else's name. I found his naturalization index entry which specifies his arrival in the US as into the port of New York in 1893.
Anna Mller married a man with the last name of Quenzer but I haven't been able to narrow down his first name yet. The Bixenman book specifies that she married a Quenzer that was involved in the dry cleaning business so I'm pretty sure he was Gottlieb's partner but can't be 100% certain about it as he may have been one of the Quenzer brothers who dropped out of the business when it was reestablished as "Quenzer & Mller".
Sophia Mller married Joseph Schmalzl. She was born in about 1871, he was born in about 1866. Their children were Otto (b. abt 1895), Catherine (b. abt 1897) and Joseph Jr. (b. abt 1899). I don't know for certain if it was them but there was another entry for a laundry business for "Schmalzl Bros" at 322 Lenox Ave, New York and a "Schmalzl, Jos." at 421 Grand Ave, New York.
I haven't found anything new about Rika Mller Susenberger yet.
If you have any information on any of these families, I'd be happy to hear from you!
