Mary Ann Sumora was the widow of Christian Sumora. She was living at 1960 Georgia Street in 1900.
She may have been the mother of Mary J. Sumora, who married Florencia Uriste (or Urioste). Another daughter may have been Josephine Sumora. The family was living in Victoria, Texas, in 1880. If this information is accurate, then Mary Ann was born about 1831 in Texas.
No further information is available for her.
