I'm afraid that I don't know of my Gustave Petzsch marrying a woman Johanna, though that doesn't mean he didn't as he was widowed in 1881 and I'm not sure when he died.
My great great great great great aunt Eve Margarethe “Marie/Mary” Heiner married Gustave Petzsch sometime prior to 1859. Gustave was in America as early as 1847, though I’m unsure if they married in Germany or America. I’ve found Gustave Petzsch listed consistently in Cincinatti city directories from the 1850s to 1890.He’s listed with wife Marie on the 1860 and 1880 Cincinatti Census (I haven’t come across the 1870 for them yet). Gustave and Mary had at least one child, Mary Petzsch Suessman, who was born on December 23rd, 1864. Up in to at least the 1870s he was the proprietor of the Main Street Shades saloon and restaurant.He appears to have retired from by 1880, however, and took up boarders in his house. Marie Heiner Petzsch appears to have died in Cincinnati on January 7th, 1881, and was buried in Spring Grove Cemetery. As for Gustave, I’m unsure what happened to him at the moment. The last sign I can find of him is the 1890 William’s Cincinatti city directory. He isn’t listed in the 1891, 1892 or subsequent city directories that I can see.
