I am not a Chenault descendant but my wife, now deceased, is the granddaughter of Maggie Eugenia Chenault. In the new Chenault Family Red Book it shows that Nancy Moore "Nanne" Chenault born 1795 in Caroline Co., VA; died 20 Dec 1861 in Caroline Co., VA; married 11 Feb. 1824 in Caroline Co., Va to Thomas Martin born about 1799 in King and Queen Co., VA; died before 1850 Thomas was the son of Obediah Martin and Ann Turner.
The father of Nancy was Samuel Chenault born before 1765 in Caroline Co., VA; died between 1810-1820; married 10 July 1793 in Caroline Co., Va to Browne/Brune Pitts born before 1765; died between 1810-1820.
Samuel's father is JOhn Chenault born about 1730 in Essex Co., VA; died 1781 in Caroline Co., VA; married by 1764 in Caroline Co., Va to Sarah Martin born about 1742; died between 1810-1820. Sarah is the daugher of John Martin and Mary Samuel.
Thomas Martin and Nancy Chenault had a son named George James Martin who married Ellen S. Chenault.
By chance is your maiden name Martin? If so there are are a lot of individuals with the surname of Martin listed under this Chenault Family.
As a matter of interest this Chenault Family originates with Estienne de Chenau (Stephen Chenault) who was a French Huguenot who left France and came to this country in the early 1700s.
