In the family bible of a descendant of George Allen Barrett (1776-1836), there is an entry for the death of Josiah. It is difficult to read, and may say that he was 8 years old when he died, or 81 years old. My father's research (Paul Barrett) suggests that Josiah was only 8, and may have been George's son, not his father.
Sincerely,
Keith Barrett
