I find her in the Census of San Francisco living with son in law, Charles Moeller in 1910, 1920, 1930.
Daughter Ella is wife of Charles.
a daughter Cecilia/Celia is living there also in 1910 and 1920.
Caharina is listed in Census as being born in Germany.
Here California Death Lists Catharina Suhr and Catharina Meclenberg so possibly this is her maiden name.
Birth is listed as 16 Oct. 1860 with Death as 4 Mar 1940 in the California death index.
any help on the Suhr or Moeller and Mecklenberg family would be appreciated.
