John Balcam, a sea captain, married Sarah Jacobs of Lynn, Massachusetts, and vital records show that Lynn was his place of residence.
John was at Mansfield, Connecticut as early as 1724. On July 28 1744 he purchased land at Salem, Massachusetts, from Thomas Lesbird. Sarah died in 1742, probably in Mansfield, Connecticut, as John Balcom, on 21 January 1744 bought property in Salem, Massachusetts, from Thomas Sesbrill, and the deed mentions John Balcom as "formerly of Mansfield, Connecticut". This deed was made when John Balcom, a mariner, was in the Isle of Jersey, and the conveyance was in French and is recorded in Sale, in French.
He sold his property in 1747 to Peter and James Murrary, and in the deed is again mentioned as of Mansfield, Connecticut. In those deeds his name is spelled "Balcam" but his immediate descendants used the spelling "Balcom".
His second wife was Hannah Proctor of Salem, Massachusetts, but there is no record of his having lived in Salem.
John Balcam was buried at Mansfield Center, Connecticut, and on his gravestone is inscribed: "In memory of Captain John Balcom who died 17 September 1782 in the 85th year of his age".
