My ggf, John OLIVER, was b. Cornwall 1 Mar. 1845. He arrived San Francisco in 1865 and worked the New Almaden Mine. He may have been related to James PEARCE (Superintendent of the mine) because he named my grandfather, Adrian Pearce OLIVER. John m. my ggm Ellen BENNEY (b. CA. 19 Jul 1855) in Santa Clar 15 Feb. 1873. They ended up in Grass Valley (he worked the Empire Mine) and had six children. After he retired (abt 1900) they moved to San Francisco. They are bur. at Cypress Lawn Cemetery in Colma.
Looking to connect John to parents, sibs, in Cornwall. His father was John, his mother may have been Alice.
