He died in Farnworth, near Bolton, Lancashire. One of his sons, another Dorning Rasbotham, is associated with Alkrington Hall, Middleton near Rochdale, a noble brick building surrounded by a park of 80 acres (324,000 m²), whose architect was Giacomo Leoni (1686–1746). In 1845 the hall and estate were sold by Doming Rasbotham – the nephew of John Lever (of the Sir Ashton Lever family) to the Lees brothers of Clarksfield, Oldham, Lancashire, for £57,550.
