Hi Mary Ellen,
Since I started this thread, a lot of West Yorkshire church records have gone online at Ancestry, so it would be worth you looking at those if you have the chance.
My sub has currently run out, so I cannot re-check my own Atkinson research on Ancestry, but I think I found something that made me doubt that my Ann Atkinson was daughter of of Mary Atkinson the washerwoman. I currently have a Findmypast sub, so will have a look on there, but I think they only have a few Leeds records.
