Richard FitzWilliam, 6th Viscount FitzWilliam (24 July 1711 - 25 May 1776), KB, PC, FRS, of Mount Merrion, near Dublin, Ireland, was an Anglo-Irish peer and property developer.
Origins[edit]
He was the eldest son and heir of Richard FitzWilliam, 5th Viscount FitzWilliam by his wife Frances Shelley, a daughter of Sir John Shelley, 3rd Baronet and his first wife Bridget Nevill.
Career[edit]
He replaced his father as Vice-Admiral of Leinster in 1728. He succeeded his father in the viscountcy in 1743 and took his seat in the Irish House of Lords. He was created a Knight Companion of the Order of the Bath (KB) in 1744 and was elected a Fellow of the Royal Society in 1747.[1] He was sworn of the Irish Privy Council in 1766. He lived for a time at Richmond Green in Surrey with his father-in-law Sir Matthew Decker, 1st Baronet, but later moved back to Mount Merrion, the family's principal seat near Dublin.
Marriage and children[edit]
On 3 May 1744, he married Catherine Decker, eldest daughter and co-heiress of Sir Matthew Decker, 1st Baronet, a wealthy merchant of Dutch origin, by his wife Henrietta Watkins, at Sir Matthew's house in St James's Square.[2] Horace Walpole thought the marriage notable enough to mention in his correspondence.[3] By Catherine he had issue including:
- Richard FitzWilliam, 7th Viscount FitzWilliam (c. 22 August 1745 - 1816), eldest son and heir, who inherited the Decker mansion and art collection at Richmond and died unmarried and without legitimate issue; by his will, he founded the Fitzwilliam Museum in Cambridge.
