Joe, The Edward Mattingly that never married was the son of Thomas Mattingly and Elizabeth Warren and was born c. 1710. The other Edward that you mentioned was the son of Thomas IV and I think that this is Captain Edward Mattingly. I have seen reference to Thomas' IV wife being a Doyne but I can't find any clear evidence of this. His brother, James, married Elizabeth Doyne, daughter of Ignatius Doyne of Charles County. Paul
