Thank you for each of these replies.
To Kayceebee5, the family whose baptism you found in 1830 is correct, it is the James
Snr whose baptism I am seeking. The James baptised in 1830 was their son.
However, I would be very interested to discover the names and dates of the other children baptised to James & Hannah if you are in a position to share with me.
It looks likely then that James Snr was not bapted at St Mary's, but in another parish.
To Greyingrey, I have traced the relevant Weatherbed line, it is the earlier ancestor who I am trying to identify. I am looking at circa 1795 (the 1900s is far too recent, but thank you anyway).
Regards to all and many thanks
Carol
