Jerome de Salis, 4th Count de Salis-Soglio

Jerome de Salis, 4th Count de Salis-Soglio DL, JP, FRS (14 February 1771 – 2 October 1836), Illustris et Magnificus was an Anglo-Grison-Irish noble, visionary, vegetarian and landowner.

Salis was the eldest surviving son of Peter De Salis by his third wife Ann, daughter of Bundespresident Antonio de Salis. His paternal grandfather was Jerome, 2nd Count de Salis.

Born in Chiavenna 14 February and baptised at Soglio 17 February 1771, he died 2 October 1836 at Dawley Lodge, Middlesex, and lies buried in Harlington-by-Heathrow, Middlesex.

In a letter of 1830 he proposed spending the winter in Madeira from whence:

'...should the Antichrist appear next year, I can easily get a passage to Chilli... by the dream I had in 1815, or rather a waking vision during an illness I had in Dublin, the application of aerial navigation to military operations will be a sign of the coming of the Antichrist.'

Salis was a friend of Samuel Wix (1771-1861), the pre-Tractarian high-churchman (i.e. pre-Oxford Movement), and paid for his Reflections concerning the expediency of a council of the Church of England and the Church of Rome being holden, with a view to accommodate religious differences (1818) to be translated into several languages.

He married thrice:

  • (1) 12 August 1797 (Shirburn Castle): Sophia (1765 - 14 June 1803), daughter of Admiral Francis William Drake (1724-87), brother of Sir Francis Henry Drake, 5th and last Bart. Mother of Petrus Johannes, 5th Count.
  • (2) 14 March 1807 (Stoke Poges): Penelope (died 20 December 1807), daughter of Dr. Robert Freeman, MD, of Uxbridge. Mother of one daughter.
  • (3) 10 May 1810 (St. Thomas's, Dublin): Henrietta (Harriet) (9 October 1785 - 26 October 1856), daughter of Rt. Rev. William Foster, DD (1744-97), chaplain to the Irish House of Commons (1780-89), and then variously Bishop of Cork and Ross; Kilmore; and of Clogher. Brother of John Foster, of Collon, county Louth, Baron Oriel, and last Speaker of the Irish House of Commons. She was second cousin to one or two of the children of Lady Bess Foster. John Leslie Foster was her brother.
