I have just found two sources on www.rootsireland.ie. Church baptism records show that Margaret Nolan was born on the 17th March 1833 to parents James Nolan and Mary Kelly. Sponsors (informants) were Michael Kelly and Catherine Kelly.

Margaret Nolan and Kyran Mitchell were married Co. Kildare 22nd September 1852. Witnesses were Stephen Nolan and Anne Nolan
