Petra, I have Alfred Prud'homme's birth certificate in French andnaturalization papers when he became a US citizen in 1880. Alfred (b 1839 France, d 1891 NY) was my husband's great great grandfather. I was thrilled to read your report about the Coffee Saloon. That was new to me.
I also have the burial receipt for Katharina Prud'homme (b 1843 Germany, d 1909 New Jersey)
I would be happy to exchange information on the Prud'homme/Wilhelm families.
