Hi. I should have read this first before replying to the other one. But I do think that my Aaron was the only Aaron Freeman in Rowan, Buncombe, Iradell and other counties in close proximity. I studied tax rolls, and census data from the first census in 1790 through 1820. The only Aaron Freeman's shown were my Aaron and a son Aaron Jr.
I hope you can get some clarification from your relative. I may do some more work and find another Aaron. If I do I will let you know,
