You have my sympathy if you have a family of baptists. I have the same problem with one of my lines. If there's a marriage after civil registration which takes place in a baptist church, it's possible they were baptists. They could be some other non-conformist denomination. Saying that, I can't see any non-conformist places of worship mentioned on the Genuki page for Llanfrechfa.

I can see a John Francis marrying a Mary Williams in 1793 in Llanfrechfa and having a son James baptised in 1802. Looks like he has a sister Elizabeth and his father was also John from looking at witnesses. That's a long gap before a first child. Have you tried neighbouring parishes for other baptisms? Can the record office in Cwmbran help?
