I'm looking for information on my Jeffers/Jeffries/Jeffreys family in Kentucky.

Moses Jeffries born 1740 married Sarah Austin born 1744 both born in Nelson, Ky
Sarah Jane Jeffries born 1766 in Ky married Hannaniah Lincoln born 1756 in Pa

I also read where the name Jefferson was interchangeable with Jeffers/Jeffries. Has anyone else encountered this issue?
