The cemetery founders Bullock and Prosser and their families are buried in OPC,
along with a dozen other early families, including the Borlands, Clinefelters, Cooks, Coons, Davidsons, Haines, Headricks, Johnsons, Paulings, Shipleys, Wankers, and Worthingtons.
Other notables include seven Oswego mayors: Jerome Thomas, Thomas Clinefelter, Durward Fox, Charles Elston, William Beckner, Asa Hess, and Albert Hughes;
and four Oswego marshals who represented law and order in the early 1900s: Thomas Clinefelter, W. A. Davison, James Headrick, and Charles Mabal.
Also interred in the cemetery is Nobel-winner Linus Pauling who was born in Portland in 1901 and died in Big Sur, California in 1994.
His ashes, along with his wife’s, were not interred in a cemetery until they were moved by the family from Big Sur to the Pauling plot in 2005.
