currently Samuel Boone, Sr and Mary Boone have a marriage date of 1703 when they are both 16 years old.
A 16 year old girl marrying in the colonies is not at all unusual for this era but a 16 year old boy is next to impossible.
Unless there is evidence available to support the 1703 date I'd either delete it outright or change to 1707 (their first recorded child being born October 1707).
