Apparently William Augustus Haskell is also buried in this cemetery [born 1834, died 1881?]. So your information came up when I 'googled' Fairview Cemetery Windsor Maine.
I live on the opposite coast to Maine, but you sound like you are close to Windsor. Have you tried looking for a city directory which covers Windsor? [It may be the Augusta city directory] It should list what cemeteries were present in that directory year.
