I am of Matchett descent. Read the 1641 depositions and you'll see Ellen Pilkington who married Matchett managed to get away with her two children. All Armagh Matchetts are descended from these two children. Ellen's mother was injured and died on the hilltop and had to be left behind. Many were drowned and the reverend was burnt in the Church.
All Matchetts of Armagh are from this reverend and the family. They were from Thurgarton, Norfolk 1500s. Prior to that it's France using machet as the surname.
