The families had their genesis in America in the late 1730ís. Three sons of Patrick Coltran of Drummorel and Elizabeth Stewart were left orphaned by the death of their father in 1717 and their motherís death before 1720. They were reared in the household of their maternal grandfather John Stewart, Baron of Physgill. The youngest of the three, David, founded the line including all of the modern Coltranes. The 2nd oldest son was William Coltrain, whose descendants moved to New England where after, a couple of generations, most of his descendants became the modern Coltrins. The name of the third brother is unknown. He was Robert or Alexander or Thomas, we donít know which. His line is mostly tied to Martin County, NC. Only a few of his Coltrain descendants were to leave Martin County during the 1700ís and 1800ís. Their name varied, being spelled phonetically as Coaltrain or Coletrain. They resided mainly at Bear Grass Township and nearby at Williamsport. The earliest name that can be tied to that line is a James on Revolutionary War records. He may have been older, serving as a prisoner guard near the end of the War.
