Hi
For births in that era in CA, most of the info I've been able to find is contained in newspapers. There were relatively few in the northern part of the state at that time (primarily in San Francisco,
Stockton and Sacramento)and they covered events, such as births, well beyond what would be considered the "local area". A website that I've found particularly useful is at URL:
http://freepages.genealogy.rootsweb.ancestry.com/~npmelton/s...Since it appears you have info about an
El Dorado county connection, you might also try the county historical museum where they have files about local families. URL is:
