and here's an even larger genealogy database:
http://feefhs.org/search/?words=lyser&Find=Find&scope=FEEFHS+Index

which references the 1872 California voter registration:
Lyser, Albert......21 in 1870......born in Prussia......34172
Lyser, Julius......51 in 1870......born in Prussia......34173

and an index to San Francisco Call Newspaper, Vital Records for the Years 1869-1891.

http://feefhs.org/fdb2/6991/6991-258.html

The SF Call index references articles on the following:
