Hi Jean,
If there are no other baptisms for a Margaret Kneale in Lezayre around this time frame, then this looks good.
I'll be working on the brothers and sisters now to see if any had a son called Patrick. My ancestor Daniel Kewish (Margaret's son) had a Patrick Kneale, aged 70, lodging with him in Cronkbourne in 1881 - which set me off looking at the Kneales!
Thanks again for your help (you assisted with some of my Costain queries a while back).
