The Wirth ancestor that I am researching is Catharine Wirth. She was married to Frank Wingerter on Sept. 13 in 1865 or 1866 in New Orleans, LA. Catharine and Frank had many children. The children for whom I have records are Magdalena, Antoine, Joseph Zepharin, Frank, Johanna Maria, Mary Elizabeth, Cecilia Clementina, Catherine, Anna Fredericka, and Heinrich Alphonse. There may also have been a daughter named Francisca. Catharine Wirth Wingerter died Nov, 23, 1913. She was living at that time in Algiers, LA, across the Mississippi River from New Orleans. Her obituary says that she was age 69 years, 7 months, 18 days when she died so she would have been born, if the obituary is correct, on April 5, 1844. The obituary also says that she was a native of Bavaria, Germany.
I am wondering if my Catharine Wirth might be one of the daughters (Katherina perhaps) of Lorenz Wirth that you mentioned.
I would surely appreciate any help or information regarding Catharine Wirth. I have little more information, but I will be happy to share what I have.
