Bective had joined Brooks’s, 19 Dec. 1810, sponsored by Lord Bessborough, but once seated for Meath on his family interest voted with government and in favour of Catholic claims.
Following the birth of his first son, 1 Nov. 1822, Lady Spencer, whose daughter Georgiana had married Bective’s younger brother George, informed her husband:
It is your regret at Lord Bective’s having a son. I have ever considered poor Gin’s children as so absolutely barred from any future accession of fortune or rank, that it actually made no impression on me to hear of that profligate race being perpetuated through that infamous channel ... It is surely better that the disappointment should take place early than late and at Lord Bective’s age it even might be looked to as probable ... As for poor Gin she must submit to it [and] exert herself to make the best of it ... These are the considerations which really make me read of the notice of Lord Bective’s having an heir with the same indifference that I should any other blackguard having one.
Add. 75937, Lady to Lord Spencer, 9 Nov. 1822.
On 21 Feb. 1823 Goulburn cautioned Wellesley against the ‘dangerous precedent’ of allowing Bective to succeed his father as colonel of the Meath militia, as it might be viewed as creating ‘a monopoly ... in favour of one family’, and urged that he be offered the custos rotulorum instead; but Bective was appointed colonel later that year.
At the 1826 general election he stood again for Meath, citing his ‘decided conviction that the concession of Catholic claims was essential’. Rumours of an opposition came to nothing and he was returned unopposed.
On the death of his father in October 1829 Bective succeeded to the Irish marquessate of Headfort. Reviewing the claims of the leading families in Meath to the vacant governorship, Wellington advised the Irish viceroy that ‘Headfort is the most important, but by English rules cannot be appointed to succeed his father’.
Bective died at Headfort House in December 1870 and was succeeded in the peerage by his eldest son Thomas (1822-94), Conservative Member for Westmorland since 1854.
