The sudden death of his father in February 1579 prompted Bacon to return to England. Sir Nicholas had laid up a considerable sum of money to purchase an estate for his youngest son, but he died before doing so, and Francis was left with only a fifth of that money. Having borrowed money, Bacon got into debt. To support himself, he took up his residence in law at Gray's Inn in 1579, his income being supplemented by a grant from his mother Lady Anne of the manor of Marks near Romford in Essex, which generated a rent of £46.
