May be it's going to be one of those unsolved mysteries

As I said earlier the first 2 children and marriage in Ashton are all close togther.
Williamson is born in Ashton 1st quarter 1856.
Mary is born in Barnsley (Worsbrough) 1858 (I think).
As John is a miner, I suppose they moved for that reason - I am assuming that Elizabeth is from around Ashton

but really we have no idea.
I am more intrigued as to what happened to John, Elizabeth, Williamson, Grace etc after 1861? Surely they must have emigrated?
