hello Marta, thank you so much for the Maintzer family history, I didn't know to much about my ancestors.I am the granddaughter of Herbert and Eula Maintzer. They did live in San Francisco and had three children: Herbert, Robert, and Frances, who are all alive and well. Herbert has one son, Jason Maintzer. Robert has two children, Kevin and Jennette(myself). Frances has two daughters, Karen and Nicole Hoyt.
Herbert and Eula did meet in detroit and Eula was from Fort Smith, Arkansas, they married in Arkansas and moved to San Francisco in the 1940's. Herbert did serve in WWII.My grandfather did pass away in 1977, two years before I was born. My grandmother Eula passed away in 2007 at the age of 94. I will let you know if I find out anything new from my relatives.
