Hello Peter, In 1821 the only place for marriages of Dissenters to take place was in the Parish Church so that rules out Baptists, Methodists and other non-conformists apart from Quakers. Both Quakers and Jews were allowed to conduct marriages. One member of my family, not a Quaker, married a girl who was a Quaker and she was required to repent of having been married in a Parish Church. I also have a record of a young couple having to go to the senior members of their Quaker Meeting with written notes of permission from their parents. If ther were no living parents or the parents were not Quakers I dare say that the Friends might then agree to consent to the marriage. However, the marriages would be recorded in the books kept by the Meeting House and possibly in the records of Dr William's Library. If the reference to 'friends' came from a parish register then it would mean exactly what it states. Cheers, Janet Heskins
