There is quite a bit of information on the Tweeds in Madison County. Jimerson Sevier Tweed (the ancestor you refer to) was one of the children of Thomas Tweed and Cecelia Sams. Thomas Tweed was one of the children of James Tweed and Rachel Neely. James Tweed and his father, William, immigrated from Ireland through Charleston between 1790 and 1795. With them was James' sister Isobell and Margaret Neely who was pregnant out of wedlock. Her daughter, Rachel, was born on the way over. Rachel and James eventually married and settled in Madison County. They pretty much started everything. William Tweed is buried at Billy Gap on Lonesome Mountain. We think Isobel is buried in Fletcher, NC with another part of the family that may have immigrated later. And James and Rachel are buried in the Tweed Cemetary at White Rock. To the best of my knowledge, we don't know what happened to Margaret Neely. (All of this has come from various sources, including oral history.) My notes have the children of Jimerson Sevier Tweed being: Sufina Tweed; Charles S. Tweed; Wolford Isadore Tweed; Napoleon B. Tweed; Sophia Tweed; Major Hamilton Tweed; Robert E. Lee Tweed; Blaine Tweed; Jancer Tweed (your grandfather); Jeter H. Tweed; and Kitty Tweed. I have his wife as: Mary A. "Polly" Chandley, daughter of Clarke Chandley and Sarah Dudley. Hope this answers some questions.
