Thank you Dianne. I have not been able to trace Henry back very far. Most of my early research was from books on Launceston Church but trying to get any documents here in Cornwall is just impossible. I think if I remember rightly Henry himself had only daughters that survived (his only son died and it was that that caused him to divert all of his energies into building the church)so even the Trecarrell name is rare here. I will keep plodding on.All the best.
