"One Negro man" was acquired by James Tyler in payment for the sale of a property in Scarborough.

"Tyler, James, came to this town about 1715. He changed his place of residence several times after 1720, but finally settled in Scarborough. He sold land in that town in 1723 to Samuel Preble "for and in consideration of one Negro man." ... James, while in this town, at first lived opposite the present dwelling house of Seth Grant, but afterwards lived at Tyler's brook." - Bradbury, p. 281
