There is a John James Dorland, native of Canada,buried at Stockton Rural Cemetery January 24, 1906, aged 54. Information came from Old Cemeteries of San Joaquin Cointy California Vol.II Rural Cemetery, compiled by San Joaquin Genealogical Society 1962, page 54.
Would write to Rural Cemetery, 2350 Cemetery Lane, Stockton, CA to see if they have any more info. Now your other fellow Peter might be there too but I don't know because my book only goes up to 1925 burials.
Stockton Public library no longer look up obits for out of towners but refer you to San Joaquin County Genealogical Society to do such for a nominal fee.
