Not sure this helps but the only James baptised in Reynoldston (now Reynalton) around this time was John James, son of Henry and Mary, 6 Aug 1809. The parents marry in Loveston 10 March 1809.
However, there is a baptism in the neighbouring parish of Loveston, 6 November 1808 for Henry James, son of Henry James (no mother's name mentioned). The father's residence is shown as Begelly. Somewhat bizarrely Findmypast.com have indexed this baptism under Begelly parish church, not Loveston. Why a Begelly resident would walk 2 miles or so across poor paths or longer by poor roads is now lost in time.
