It might be worth remembering that a Dinah LARDER was bap at Covenham St Bart, 26 July 1818, dau of Thomas and Ann ... the only Dinah in the C St B baptisms 1760-1836 according to the IGI.
Thank you I shall bear that in mind she certainly sounds the better option - I am fortunate that most of the kids were born after 1837 so at least i can get birth certs to prove it
