NC to GA Cook's

I am looking for 2 families in particular.
Jim Chafon Cook was a son of James Cook(son of Edward Cook).He married a daughter of Jesse Cook whose name was Betsy.They were born around 1828 in NC and moved to GA soon after their marriage, I think probably around 1850.
Also, Jim's sister, Nancy Cook married Jesse Silvie and they too moved to Georgia.

I know nothing more, but would love to find some of you distant cousins out there!
