Re. misspelling, is the name Warton on the 1802 Stapenhill marriage quite clear? The reason I ask is that FindMyPast has the baptism (transcript only) of a Hannah WaLton, 1777, Church Gresley, parents Wm & Mary. Church Gresley is just spitting distance from Caldwell/Linton. The parents married 1776.
Yet to find a marriage/death for a Hannah WaLton to rule her out definitely as a possible candidate for Hannah WaRton.
Just a thought.
