Pike family of Gloucestershire and Somerset

I've recently been looking for Pikes in Gloucestershire and Somerset. My earliest known Pike ancestor raised his family in Alveston, Gloucestershire, but the censuses say he was born in North Petherton, Somerset sometime in the 1790s. There are a few Pikes listed in the IGI for North Petherton, but I can't find one the right age to be my James. The closest one seems to be a James Pike, son of James Pike and Sarah Parker, who was christened in 1782.

I also found a John Pike who was born in North Petherton around 1794, who raised his family in Olveston (just down the road from Alveston). I suspect that John and James may be related, but I have no idea how at the moment.
