To my knowledge, I am not related to the Hill family, but bumped into the name Swinfield Hill while researching my Wright family. My ancestor Solomon Wright/sometimes spelled "Right" (b. Abt 1775, d. 1860-1870 in Yancey Co., NC) named one of his sons Swinfield Wright. Solomon Wright shows up in the Burke Co. census records as living near Swinfield Hill. Solomon lived in the part of Burke County which later became Yancey Co., appearing in the Cane Creek township. There were usually some of the Hill family living near my Solomon. Both the Hills and the Wrights married into the Hughes family.There are three articles in the Toe Valley Heritage Vol II (I believe it is that second vol.) on the Hill family. These books by Lloyd Bailey Ph.D. are on the Yancey, Mitchell, and Avery Co area in case you are not familiar with them. In an article entitled: "Some Hill Families," it begins with a Robert Hill from Dublin Ireland who settled in Va. and left a will dated 1777. He had at least two sons, Thomas, and a Swinfield b. around 1759. It continues with later descendants, including others who carried the name Swinfield. Yancey County borders on Tenn,--Unicoi and perhaps Carter Co. Several of those Yancey Co families moved back and forth into Tenn.
