Gov. Alexander Martin: Biography of a North Carolina Revolutionary, by Chas. D. Rodenbough, 2004, p. 108
Elizabeth Strong arrived in Rockingham County at least by September 1783 when she purchased, in her own right, 188 acres on Double Creek of Fisher Creek and north of the Dan River. she had been born in Virginia about 1750, the daughter of Thomas & Ruth Baker Lewis. About 1769, she married Thomas Strong of Halifax County, Virginia. They located on Sandy River and had at least five sons. Thomas became a 'Long Hunter', a term used for men who in October each year left home, to go hunting over the mountains until April. It is estimated that their profits in one season could exceed that of a farmer for a lifetime. Thomas Strong disappeared during the early years of the revolution. He may have died in battle, been killed by Indians, or just never returned home from one of the long hunts; the latter is a good possibility because Elizabeth was never identified as a widow.
During the Revolution, Elizabeth's brother-in-law, John Strong, moved south across the border into Rockingham County, North Carolina, where she bought her property in 1783. All those who settled in this neighborhood around Sharps Creek, were friends and relations from Virginia including James Holderness, Lewis Irion, William Langston Lewis (Elizabeth's half-brother), Mary Fields, John Fields, Valentine Allen, John Pratt, Sarah DeGraffenreidt (widow of Baker DeGraffenreidt) and Turbefield Barnes.
Elizabeth Strong built a home on her property for family and eventually met Governor Martin. ...their relationship was never sanctified through marriage. The reason that may have been used by either party could blame the house full of children Elizabeth already had or the lack of proof that she did not have a husband somewhere. Sometime in October 1786, they concieved a child. (Alexander Strong Martin)
