Help with Parish records -Somerset

[turnera]

Hi can any1 assist me with trying to find out further details about Thomas Sheppard whom I believe was born in 1799 in Whitchurch, Somerset. I have census details from 1841, so I ideally now looking to find ways of find out his parents from parish records or brothers or sisters. I believe he married Ann Handford which was in the parish records in St Mary's Bitton on 11 January 1825.

I would much appreciate help if any1 can point me in the right direction.

Regards
Andrew
