Not that I know of at this time. Since Sylvester was a young man of 20 when he followed his ox to Oregon, he may well have gone with other family members. I do know that he did not stay in Oregon, but went to California for several years. He returned to Oregon in 1857 where he married a women named Livonia (?) and farmed in Clackamas Co. He moved to Columbia Co. WA in 1881. Sometime between 1857 and 1881 his first wife died and he married a Martha (?). He and Martha are buried in the Dayton WA cemetary. Any of this help?
