The last two children, Nancy and Bould were baptised with mother named as Elizabeth. However, when Bould died an infant, the mother is Isabel. After 1788, Isobel was known as Elizabeth (Isobel is a diminutive form of Elizabeth), but after James died, she reverted back to Isobel.
7 March 1794, Isobel's husband James died, leaving Isobel with no support (so "Poor")..
25 March 1794, "Bould son of Isabel Mather, Poor, of Great Bolton" died and buried at St Peter's, aged 1.
After James died, Isobel remarried. There is a marriage for Isabella Mather spinster and John Robinson (weaver) 8 Mar 1797, and then another to John Lever (widower) and Isabella Mather (widow) on 24 Dec 1798 with witness Richard Haslam.
