FYI a while back I bought a "funeral card" for Elkanah Mills, who died at "Riverside Farm" in Centralia in 1893. It has a little information about him, and a small photograph. If there is interest I can send or post a scan of the card.
The card says, in part:
In loving memory of Elkanah Mills.
Born: Sommerset, Pulaski County, Kentucky, December 20, 1818. Died: "Riverside Farm," Centralia, Washington, Friday eve, December 1, 11:45 O'clock, 1893. Aged 74 years, 11 months, 19 days. He came west in 1847, and to Centralia in 1870.
