I'm trying to find a 1891 Census for Mary Barr (12) 1881 Census born Kilwinning, Ayrshire. She is the step daughter of Peter McPhearson (coal miner) and her mother is Elizabeth Barr b. 1839. Ireland. She has two brothers - James Barr b. 1867, Kilwinning, Ayr and Robert Barr b. 1857?, Ireland also coalminers. I think their father was a Robert Oliver a Colliery Manager.
