I found several of the persons on my list at Mount Hope Cemetery in San Diego (see this post on the South San Diego County Graveyard Rabbit blog about the cemetery).
In Section E, Lot 33 of the Masonic Division of Mount Hope Cemetery are the graves, and gravestones, for:
* Eva Etta DeFrance (1891-1940)
* Howard M. DeFrance (1881-1937)
* Joseph W. DeFrance (1865-1937)

Who are these relatives? I posted a list of descendants of Samuel and Mary Ann (Underhill) Vaux here. Leava A. Smith (1866-1958) was the first wife of David Devier Smith (number 3 in the noted report), and they had one daughter Eva Etta Smith. David D. Smith is the brother of my great-grandmother, Della (Smith) Carringer, and therefore my great-granduncle. Eva Etta (Smith) DeFrance is my first cousin twice removed.
