Sir Osborne Ichyngham or Echyngham (died 1546) was an English official and landowner in Ireland.
The change in spelling of the surname may represent an appropriation of, or assimilation to, the place-name Ditchingham, nearby to Barsham.
By 1515 Ichyngham had emerged as the confidential agent and messenger of Sir Thomas Spinelly, English Resident Ambassador in the Netherlands.
[1] In February 1514–15 his presence is requested by Spinelly, in his message from Antwerp advising Wolsey that a marriage between Charles Brandon (Lord Lisle, Duke of Suffolk) and Queen Mary, Henry's sister, was rumoured.
[9][10] The Dunbrody lands were called a "waste" estate,[11] but commanded the outflow of the Three Sisters and the eastern shore of Waterford Harbour from Ballyhack down to Duncannon, across the Hook Peninsula to Coole, Ballyvelig, Tinnock and Curraghmore, and crossing below the estates of Tintern Abbey to the inlet from Bannow Bay at Ballygow (Poulfur).
