His gravestone reads: "4th gen, Fones Greene, son of Capt. James Greene, died July 29, 1758, aged 67 years." This would make his birth year c1691.
Fones Greene married first to Dinah Battey, who drowned a few days after their marriage in 1711. She was sailing across the Bay from Newport to Jamestown.
Fones's uncle Samuel Fones married Ann Tibbetts, aunt of his second wife Rebecca.

Fones resided in the house which he inherited, built by his father c1687, in the Buttonwoods/Nausauket area of Warwick, RI, bordering on Greenwich Bay. A second house was built in its place in 1715, and is still standing today, in 2008. A large part of the Greene estate was sold in 1868 to the Buttonwoods Association, which developed the area with homes and a campground on the shore.
