GA Habersham Co. Smiths

I am descended from Gilbert Smith, born c1810 SC, who married Catherine Hambrick 1836 in Habersham Co., GA. They eventually made their way westward and ended up in Columbia Co., AR where both died in 1850s. I believe my Gilbert is related to Aaron and Leonard Smith of Habersham Co., GA and that they all might be sons of James Smith. Anyone working on these Smiths?
