Mary Sewell in Carlisle

Hello:

My wife's tree has a Mary Sewell b ca 1816 in Stanwix, Carlisle, married William Dean (b Caldgate/Dalston area) in 1842. Mary's mother was Ann and father Robert was a labourer, but stuck for any more info on them.

Curiously Audrey has a Mary in her tree same age/occupation/place of residence (Botchergate Carlisle), but the parents are different and we agree it is a different family, though possibly related in some way.

Any info on our Mary's parents would be most welcome until I can get myself up to Carlisle to research myself.

Gordon.
