My GGGrandfather was John McCONVILLE whom I've traced to the British census of 1871 in Tow Law, (Wolsingham), Co. Durham. John was age 53, a mason's labourer, born Armagh, Ireland. Also his wife Sarah, age 52, born Parish of Craggan (presumably Co. Armagh), their daughter Margaret age 19, born Leadgate, Durham and Sarah McCONVILLE, age 13, boarder, born Ireland.
John, his wife Sarah and Margaret (and her family) came to Fayette Co. PA about 1880/81, apparently missing both the US Census of 1880 and the British Census of 1881.
I have not been able to locate Margaret's birth record.
Any connection or information about this family very much appreciated.
