I didn't find anything on either John nor Urias in Ancestry nor in FamilySearch.
However, there are two volunteers in El Dorado County who will look up births, marriages, death, cemeteries, obituaries and city directoris. You will find their contact info at www.gengathering.com
, California, El Dorado County. You'll need to sign in first.
Also the Roots and Gold Dust Genealogical Society, www.rootsweb.ancestry.com/~cardgs/
has a Research and Resources tab that tells you about the organizations within the county. Successful Searching!
