Hello Brian
Thanks very much for for your help. It did cross my mind about being baptised later in life. My Frances Curgenven married George Gay in 1751, and was baptised in 1739. Her burial was in 1788, aged 68, making her birth about 1720 baptised at 19 and married at 31. This makes better sense. I take it there is no registry of births. Regards. Paul.
