The year of the birth of son John would be about 1631 based on the age at death on his tombstone as published, but this must be incorrect. The list of church members in January 1658/9, when describing a family, enters the children in birth order, and for this family John is placed between Martha and Samuel, strongly suggesting that the age at death as given is not correct, and should be 38 rather than 48. This is consistent with his date of marriage.
