Ann Moody married her cousin, Thomas McCuiston, 15 Sep 1756 in Guilford County. Birth and death data are probably from Leona Bean McQuistion's book since the gravestone for her and Thomas is quite modern and was erected long after her death. A monument placed in the McCuistion Cemetery in Shelbyville, Tennessee, is engraved with names of people to whom it is dedicated. Couples are: James McCuistion and Sarah Behol, Thomas McCuistion and Ann Moody, Robert M. McCuistiion and Elizabeth McWhorter, Joshua McCuistion and Mary Elizabeth O'Neal. Noah Wesley McCuistion and Elizabeth Jordan, Carleen McCuistion and Floyd Garwood, Robert Jordan Garwood and Theresa Testman. A photo of the memorial stone is available at Find a Grave Photo. Among Thomas's and Ann's children is a Joseph, b. 25 June 1776, d. before 1821.
I have done little research on the children of Ann Moody and Thomas McCuiston.
Thomas is probably buried in a Guilford County cemetery, but I haven't found the name. The Shelbyville, Tennesse, monument implies that his parents were James McCuistion and Sarah Behol, but Leona McQuestion's history gives a different name, Jennet, for his mother. Possibly she was Sarah Jennet or Jennet Sarah.
