The following items are from the Minutes of the Court of Pleas and Quarter Sessions of Craven County, North Carolina.
In short, James Roach was the father of Charles and David Roach of Craven County. His wife, and the mother of Charles and David, was Katherine Johnson, sister of Jacob Johnson. After James’ death in 1745, Katherine married Thomas Swaffer. I don’t believe Katherine and Thomas Swaffer had any children together, as when Thomas Swaffer dies in 1778, his estate was minimal and was administered by Charles Roach, Katherine’s son by her previous husband, James Roach.
