Mary did not remarry, and arranged for the education of her children by a clergyman, William Rawlins.
[1] He matriculated at Magdalen College, Oxford, on 6 November 1670, travelled on the Continent from 1673 to 1676, and received his Master of Arts on 11 July 1676.
[2] When Fulke Greville, 5th Baron Brooke, succeeded to the peerage in 1677 and vacated his seat for Warwick, he supported Digby to succeed him at the ensuing by-election, which occurred in May, without opposition.
He was accounted a member of the Country Party, but never took his seat, as he died on 29 December of that year.
Digby was buried at the family estate of Coleshill, Warwickshire, and was succeeded by his younger brother Simon.
