I am seeking the name of Howell Powell's daughter who married my 4th great grandfather Richard F.Gaggin.

This Howell Powell was born in 1730 in Derbyshire ENG and became involved with the Methodist Church in Bandon. His letters are included in John Wesley's. This daughter was baptized assumable in Bandon and by John Wesley. Any information would be much appreciated. I can't seem to hunt him down.
