My line of Abernathy's were in Cherokee County, Alabama in 1880s. My grandmother, Bertha Ann Abernathy b.1889 was born in Cherokee County. Her father was Zephaniah (Z.N.)and he was born in Cartersville, GA in 1852. His father,Isaiah, was born 1809 in Lincoln County, NC. Z.N. had a brother, Jeptha (Jep) b. 1849 in Georgia and he had a son Robert. Could this be your line?
