Reuben and Jane (Jenny) had a son named Edward born ca. 1770 in Sussex Co., NJ. I assume the Edward you ask about is a grandson but I don't know from which son. I do have a photocopy of his 1818 marriage bond to Elizabeth Jackson. There was also a Henry Kemp in the same area of KY in the 1790's and he signed a marriage bond of one of Reuben's daughters. Maybe Edward is his son. If you would like a copy of Edward's marriage bond, let me know and I will send one to you.
