I am searching for a female relative, born 21 Aug 1879 in San Francisco, CA. By the 1880 census she was in Tuolumne County with relatives. Her mother's name is unknown and she was unwed. The mother was probably Mexican and Catholic, if anything. I have been searching for years and always told that all pre-earthquake records have been destroyed. I have also contacted the church and county in Tuolumne County to no avail. Does anyone have any suggestions for locating birth or other records that may have contained her mother's name in this period? Thanks.
