What Swayzes are you related to? This book has also been referred to me by an Adams County, Miss. researcher. Richard Swayze,Jr. and his son Gabriel Swayze are listed in the 1778 will of Robert Robinson who was killed on his farm near Natchez, Adams Co, Miss. in 1776. Robert's wife, Rhoda Horton was the sister of Richard Swayze's mother Sarah Horton.
