My family tree contains a Sarah Lagan, who was born about 1827 in Maghera. On September 8, 1853 Sarah married John N. Convery in Brackagh, Derry. John and Sarah had eight children; all born in Lavey: Mary, John, Mary, John, Patrick, Robert Henry, William James and Charles, my great grandfather. Sarah died on October 12, 1873 and is buried with her husband, John, at St. Mary's Old Cemetery in Lavey Parish in Derry.
I would appreciate any additional information.
