FamilySearch has Samuel Williams born at "Moor, Flintshire" in 1764. Moor referes to Moor Lane Saltney, Hawarden (not Halkyn Moor)
Samuel must have been born between 1756 and 1771 (so aged between 20 and 35 when he married Ann aged 23 in 1791). Samuel was a labourer so may expect his father to be the same. Possible baptisms:
