Calcraft, who was elected to Brooks’s on 14 Feb. 1817, was brought into Parliament for his father’s borough of Wareham at the general election of 1820. Described by Sir James Mackintosh* that year as ‘a very sensible young man’, he was inactive compared to his father, whose lead he followed in supporting the Whigs, dividing silently with them when present.
He again fell ill in early 1826,
quite in a deplorable state of insanity and nearly hopeless of life - by Methodism and fanaticism. The duchess of Beaufort has got hold of him and with her horrid creed and her books and her various engines of assault, she has fairly turned his brain, and [George] Tierney* told me that he was quite despairingly mad and under mad doctor’s care.Add. 75938.
No doubt because of his ill health, he was not brought forward for Wareham at the general election in the summer of 1826. However (unless it was his brother Granby), he was well enough to attend a Whig meeting at Brooks’s in April 1827, from which he carried to Lord Lansdowne a message urging him to join the Canning ministry.
marriage was a real love match and not the brilliant one that was expected of her. She met my grandfather, John Calcraft, in Italy. He like her, was a most beautiful person up to the last, but as a young man he must have been dazzling - many people mistake his portrait for that of Byron - but I think he was undoubtedly more handsome. Before his marriage he was a close friend of Pauline Buonaparte’s and she gave him a quantity of Napoleon’s books, some of his lace ruffle and some locks of his hair.R.D. Ryder, Calcrafts of Rempstone (typescript, 1975) in Dorset RO, Ryder mss D/RWR Z7, pp. 43-45.
He presumably supported the Wellington administration, in which his father-in-law was postmaster-general, and he served as deputy to his father, who joined the government as paymaster of the forces in June 1828. He began to take an active part in local affairs, chairing the anniversary meeting of the Wareham Church Missionary Society, 21 Aug. 1828, and he stood in for his father at the mayoral election dinner in Wareham, 13 Sept. 1830.
After the final madness and suicide of John Calcraft in late 1831, Agar Ellis noted that ‘I fear much the effects on his son’s health’.
one of the most magnificent old men that I have ever seen, and I should think had given his wife cause for anxiety in the days of old; and indeed at the present time one can recognize his brilliant eyes and magnificent hair and build in many a person round who has never heard his name.[J.E. Panton], Fresh Leaves and Green Pastures, 28.
His estate was inherited by his elder surviving son William Montagu (1834-1901), the last of the male line, whom Panton described as ‘a gentle, melancholy, unambitious man’.
