I'm looking for my Great great grandmother who - according to her naturalization records was married in Napa, California the 20th March 1925. I do have a discrepancy, as the marriage date on her husband’s naturalization record states XX (hard to read) March 1918.
None of the online databases (Ancestry or Myheritage) have anything from California from that time.
Their names are Vilhelmine Victoria Marie Olsen (b. 22/3-1864) (Called Marie - and sometimes with her second married name Vogel) and Ceasar Christian Boetticher (b. 14/2-1858)
Any help is appreciated.
