Hello Rodger
I am afraid I may not be of much help as after a two year search the only two perfield/purfields I have in my tree are my gggrandparents Nicholas and Mary his wife they came to England from Ireland about 1840ish and lived in Liverpool Their daughter was born in Ireland 1842 and this is all I have I am afraid The family name after that was Toft as their daughter married a Francis Toft from Derbyshire Sorry I'm not much help
regards Lynne
