Jeni: It is an error to believe that the San Francisco records are gone because of the 1906 "Big One". Many records were never lost and others have been reconstructed. Obviously, some are completely gone. I would suggest that you make specific queries of this group, each of the CAGenWeb counties and NORCAL. Not too long ago there was a great deal of information on NORCAL re your specific Sanford branch. I hope you have better information on your Miller branch than I have been able to find on mine. It is an extremely difficult surname when you have little information. Chico State University should have a fair amount of information on your Bidwell branch that you may be able to access from the campus library via ILL. Good hunting, Lewis M. Ruddick
