craig, Elizabeth Pickersgill is in 1861 living at 8 triggs houses, greasborough road, she is now a widow, as joseph had died inbetween census. With her is Martha, who in dec quarter of 1852 married william cokeley, and they have a 6 month old child, elizabeth ann. Reuben in 1861, is married with a family and remains in barnsley. I do not have online resources and have not yet looked up the census in the records office, my basic search just put the family in the district of ecclesfield, but if you have a more detailed address that would be good. Joseph and eliza were married in 1815, and in 1841 have two children, so it is probable there were older siblings who are in seperate households due to marriage. The fact that ann stays close to elizabeth would seem to suggest a strong possibility that they are mother and daughter. If you come up with anything else let me know. thanks.
