Looking for Louisa M Millmeister from Germany

Earlier this year we took a short family vacation, and as we were passing through a couple of towns I was able to stop in some county recorder offices and pick up some death certificates (It was less fun for my wife during those parts). One of the certificates I picked up was for my 3 Great Grandmother, Louisa M Millmeister. She died on 5 August 1927 in Stockton, California, as the wife of Gottlieb Gall.


One of the new pieces of information that I got off of this record was her birth date, 158 years ago today, on 25 October 1853. Other new info was that she was born in Germany to Carl and Wilhelmina Millmeister. Sweet! a birthday, place, and maiden name from her parents! Unfortunately, I haven't found much other info on her. I found that she was married in San Jose, and in the 1880 census it says that she is from Schaumburg.

So now I am stuck again. I haven't done research on German lines before, and am having trouble finding some good online resources. It doesn't help that I can't read German.
