Charles Tennyson d'Eyncourt

Charles Tennyson d'Eyncourt (20 July 1784 – 21 July 1861), born Charles Tennyson, was a British politician, landowner and Member of Parliament (MP) for Stamford from 1831 to 1832 and for Lambeth from 1832 to 1852. He is also known for his social pretensions and his graceless behaviour towards his nephew, the poet Alfred Lord Tennyson. He was educated at St John's College, Cambridge.
He was the younger son of George Tennyson, who bought the family seat of Beacons, in the village of Tealby, Lincolnshire, along with 2,000 acres (8 km²) of land, and came in time to own a large part of the village. George, as is well known, disinherited his elder son George Clayton Tennyson, the poet’s father, at the age of 12, putting him into a career in the Church, for which he felt no calling; and bestowed all his fortune on Charles.
As a result, there was bad blood between the penurious Tennysons of Somersby, where George Clayton Tennyson had the living until he succumbed to drink and depression, and the opulent Tennysons of Beacons, who fancied themselves not only the wealthy but the socially superior side of the family. Old George’s wife Elizabeth Clayton was supposed to have descended from the Lords of Lovel and d’Eyncourt, and also from King Edward III.
A ruined castle was part of the property, and Charles wished to establish a noble lineage for himself with a title and a castle. When his father died he changed his family’s name to Tennyson d'Eyncourt. Beacons was renamed Bayons, to make it sound like a Norman castle, and it was extensively enlarged and rebuilt in the style of a Gothic castellated manor-house.
In public life Charles Tennyson d'Eyncourt was for many years MP for Lambeth, and was made a Privy Counsellor in 1832. Also in the 1830s, along with Augustus, Duke of Sussex and Admiral Sir Sidney Smith, he was one of the prime movers in a plan to have the Order of Knights Templar revived as a British order of chivalry. In this he failed, and he also failed during 1839-41 in an attempt to revive the d'Eyncourt peerage for himself and his heirs. In February 1829 he was elected a Fellow of the Royal Society
He published, in 1850 a book of poems, Eustace, in memory of his youngest and favourite son who had died abroad; it had the misfortune to appear at the same time as Tennyson's In Memoriam, and suffered greatly by the comparison. Charles thoroughly disapproved of the poetry of his nephew Alfred (Horrid rubbish indeed . . . a discredit to British taste), and the latter’s appointment as Poet Laureate in the same year and subsequent offer of a baronetcy caused him outrage and chagrin. He did not live long enough to have to endure a 'Somersby Tennyson' being elevated to the peerage.
The Tennyson d'Eyncourt family eventually gained its baronetcy at the beginning of the 20th century and still continues. Two of its later members had notable maritime roles. Charles's second son Edwin Tennyson d’Eyncourt (1813–1903) entered the Royal Navy and became an Admiral. Undoubtedly the most significant member of the family was the naval architect Sir Eustace Tennyson d'Eyncourt (1868–1951), the First Baronet, who was the Royal Navy's Director of Naval Construction in the first decades of the 20th century.
