Where are you finding this information? I have a lot of Hoffpauirs in my database, and I can't locate any of these with the dates you have and parentage you have. For ex I have a Uranie Hoffpauir b. 1910 but none b early enough to have a child b. 1864. What does "Hoffpauir, Marie (Uranie) mean? I have many Marie Hoffpauirs, but none matching the birth date you have.
