I am researching a Nicholson family and I'm stuck on a John Nicholson who had married Ann ? and they had 3 children baptised in Sunderland - Margaret (1786, Malling Riggs, Sunderland), Jane (1789, Robinson Lane, Sunderland) & Morrison (1793, Malling Riggs, Sunderland), all non-conformist chapels.
Can anybody help mke find a marriage record for John Nicholson & Ann? I would also like to verify John's parentage. Any help would be apprec8iated.
