I am making an assumption that the "Levi, of Ezekiel" in the marriage entry belongs in this family group, because the dates fit. Also, the names of their children reflect the names of the previous generation.
His gravestone in Historical Cemetery #21 on Weaver Hill Rd. has been photographed. It reads: "In memory of Mr. Levi Whitford, son of Mr. Ezekiel and Sarah Whitford, who died Jan 22, 1843 aged 44 yrs 6 mos & 25 days." There is a poem at the bottom which has not yet been deciphered.
