Recollections of an old man: seventy years in Dixie 1827-1897 (1910)
BY: Sullins, David, 1827-1918 p 14
" My ancestors were Scotch-Irish. I remember while yet a boy to have heard my
father tell that somewhere about 1750 his father and two brothers, came from "the old country" to America. These brothers were Scotch-Irish, and all unmarried. They separated after they arrived in this country. One stopped in Pennsylvania, and married there; one went to North Carolina, married,
and located near Guilford Courthouse; the third came to Virginia, married a Miss Mays in Halifax County, and settled on Dan River.
This was my grandfather. Here my father was born. When he was twelve years old, his father came, among the first pioneers, to Tennessee, and settled on Poplar Creek, in Knox (now Roane) County, near Oliver Springs, in 1795. Here my father grew up to manhood in the wilderness of the new country.
He had one brother (Joseph) and three sisters. These sisters married Dr. William Farmer, Joseph Stubblefield and William Gent. Some of the descendants of these families are still here in East Tennessee.
Rev. Joseph A. Stubblefield, D. D., who for many years was President of Centenary Female College, is the grandson of the Stubble-
field who married my paternal aunt."
