Haven't yet found a likely William and Ann marriage, but for John and Mary, there is a marriage for a John Evans and a Mary Payne at Sellatyn on 5 Feb 1810. Botp, banns, both signed X, winesses, Thos Jones and what looks like Elizabeth Richardson (X).
Could be where John and Mary came from on the online trees, but instead of looking closer to birth location, they picked a John Evans marrying a Mary on the other side of Wales. Sellatyn was one of the various birthplaces William gives on censuses.
