Hm, that's interesting, thanks. I did wonder about the Yorkshire Accent thing, but the place was consistengly spelt Tagstones. Perhaps it just changed over time. Birtin became Burton for instance.
As an aside, a fellow Donkersley researcher took years to find her ancestor's birth record. The child was the son of a Yorkshire soldier and an Irish mother, and the child was born on board a ship bound for India. Not only was the poor child, a boy, listed as a girl, but his mother's name was was recorded as Dinhersley! (the result of an Irish lady telling an Indian clerk her Yorkshire name)
