Littleton's sister, also called Frances, had married Moreton Walhouse, a member of a business dynasty with valuable investments in the Walsall area. Their grandson, Edward Walhouse was made heir to the Littleton estates, on condition that he change his name to Littleton, which he subsequently did. Heir to two fortunes, and thus a very rich man, he also became by far the most illustrious of the Littleton family politically, an important reformer and an active parliamentarian in both Houses for over fifty years, he served as Chief Secretary for Ireland in the 1830s.
