Thanks for the info. Here's some additional info that I got from a librarian in Rowan County:
Hello Mr. Aycock,
We haven't been able to find any more on Reddick except the Aycock Genealogy book mentions a brother Jonathon, who died in Georgia in 1825 and left Reddick's 6 children as heirs--one of the children named Reddick Jr. The deed mentioned in 1803 was in the Davidson County area and he could have been there all along.Rowan County once was a huge area and 26 counties were eventually formed from the area.I did not find him in tax or other records in Davidson.I did find one more deed for him:Deed Book 15, page 403 Reddick Haycock bought 50 acres on Duches Creek from Christian and Barbara Michael, witnessed by David and Joseph Michael on Nov. 6, 1797.This is the same piece of land he sold in 1803 to Peter Bierly.
