This is not the Thomas Mather and Catherine Lawton family (1844-1920). They married 1864 at Christ Church, Bolton. There is only one other possible Bolton, Lancashire Catherine Mather death at Farnworth in 1898. However is is not likely Catherine would have a child in 1868, when aged 61. She must have remarried or died elsewhere.
