Robin, I've also been looking for this family for the last 50 yrs!John F Dickson md. Rebecca Abernathy28 Jan 1799 in Brunswick Co, VA.They had 8 ch, but I only know the names of Eliza Jackson Dickson (my line), & Clara. There were 2 other girls & 4 boys. John F. d. in Brunswick Co in 1829 & Rebecca (1778) d. between 1840 & 50 in Giles Co, TN. She went there w/her bro, Dan'l, after John died. She's on the 1840 cen, but not 1850.
