There were two of the 3 Forney brothers from Lincoln Co North Carolina present at the Battle of King's Mountain: Peter and Abraham (Abram). They were sons of the family of Jacob Forney (1721-1806) and Mariah Bergner (1725-1810, from Bern, Switzerland). The family resided in Lincoln County NC near what is now Denver, NC.
All three of Jacob's sons participated in the Rev War. The eldest, Jacob, later moved to Burke Co NC and had 11 children. The second son, Peter, resided all his life in Lincoln Co, NC and was a prosperous Plantation owner; he and wf Nancy Abernathy had 12 children, most of whom later moved to Alabama. The third son, Abram married late in life, remained in Lincoln Co, NC, and had only one child to survive to adulthood. I descend from both Peter and Abram Forney of Lincoln Co NC.
