I am looking for information on the family of Fredrick Clifford Ahrens. He served as a San Francisco Police Officer from the late 1940s until probably some time in the late 1960s or early 70s His first marriage was to Joan Fitzgerald in 1950 in San Francisco. They had one daughter, Christine who was born in 1951 also in San Francisco. I have been told that he died in the mid 1990s and I believe he might have been living in the Stockon or Lodi area of California His father's name was Harry J. Ahrens and he was probably born at the turn of the century I believe in California but I am not sure. His grandfather's name was Adolph and he was born in Bremen, Germany. I am most particulary looking for the children of his second marriage that took place about 1953-1954 in California. Any help is appreciated.
