The piece that was left in the ground was completely blank, so it must've been sheared off right at the bottommost line, leaving the year of death a mystery.
It was also strange that there was only this one marker. There could be other headstones, toppled over and covered by leaves and brush, but we couldn't find anything.
As for who Charles Pollitt was, here's some information I was able to dig up:
According to an 1881 English census, a Charles G. Pollitt resided in
Radcliffe, Lancashire, England born around 1872 (National Archives of the UK 1881:RG11, Piece: 3870; Folio: 6; Page: 3; Roll: 1341925). Pollitt’s father, Charles Grimes Pollitt, appeared to have immigrated to the United States, as a Charles Pollitt of his age and English origin is listed as entering the pension care system of the National Home for Disabled Volunteer Soldiers while residing in Connecticut after serving 36 months with a unit in New York (National Home for Disabled Volunteer Soldiers 1899: 291). It is unknown when the junior Charles Pollitt indicated on the grave marker may have journeyed to the United States or when he died. His father’s pension of $12 per month for a hernia injury suggests the family was not extremely wealthy, perhaps leading Charles G. Pollitt or his family to find residence at the Colony.
