I'm researching the Rixners from Germany. Our ancestors ended up mostly in Pennsylvania. Where did your Rixners originate -- Germany? France?
I have some info from the 1880 census that has very many Rixners in Louisiana -- I did not see your ancestor Numa listed.
From the 3rd ward, St. John the Baptist, 1880 census lists Bebe, Ester, Joseph, Silver, Marie, and Victorin Rixner (apparently all one family).
