However do NOT look for a marriage in a Non Conformist Church between 1753 and 1837. During this time, apart from Quakers and Jews, all marriages had to be at a Church of England. Marriages were not valid if performed elsewhere.
Non Conformist Registers become more widespread after 1780 as Nonconformity grew. Again County Record Offices can advise which Registers exist and they will probably have a copy of these. Researching Nonconformist Ancestors can be more complex as fewer records survive. However for those who were active members there is sometimes a wealth of information in Church minute meetings, etc. The established Church of England obviously viewed the growing tide of Non Conformity as a threat although it is difficult to understand their antagonism from a Christian viewpoint.
