3rd Jul 1780 - 8th Mar 1873

Claimant or beneficiary


  1. Son of Robert Delap and Mary Ann Bogle, brother of James Bogle Delap (q.v.) and Samuel Francis Delap.

  2. Married (1) Catherine Foster [d. 1842] 05/09/1805 (2) Mary Sankey, St Mary Bryanston Square 09/07/1845. Four childen with his first wife: Robert Foster, Catherine Letitia Drummond (d. 1827), Mary Anne Sarah (d. 1841) and Henrietta Jemima (d. 1831).

  3. Of Queen Anne Street, Westminster, 1807. Described by his wife's uncle, John Foster (Chancellor of the Irish Exchequer) as "a good man of business resident in London where he acted as a merchant and has a West India property of his own to look after", 1811.

  4. Resident at Geneva in the early 1820s; in September 1821 his wife wrote home that "The Prince and Princess of Denmark are very gracious to me for being Augustus Foster's relation".

  5. Subscribed to Samuel Lewis' 'A Topographical Dictionary of Ireland' 1837, when his address was given as Monasterboice, Collon, Co. Louth. Lewis noted that Delap "has a large estate here and is planting on an extensive scale... a spacious mansion is now being erected". He was a Governor of Drogheda Infirmary by 1842. His first wife Catherine died that same year.

  6. Resumed by licence in 1861 his family's original surname of Dunlop. Delap is how the name Dunlop was pronounced in Ayrshire in the late 1500s; his ancestor, Hugh Delap arrived in Sligo in the early 1600s from Ayrshire). "He failed as a merchant in Scotland, left his inheritance to his sisters and came to Sligo. He was one of the first Protestants who lived there. He grew rich and died at Sligo aged 60. Miss Aitken (his wife) came from Scotland to Sligo and was robbed by a gang at Barnkmore (sic. probably Barnesmore). Their children remained unbaptized for years until a Mr Rosecraft came and baptized them. Hugh Dunlop's widow married, secondly, a Mr. Galt, a Scotsman. Three days before the massacre of Protestants in Sligo, Lord Taafe sent the two families of Dunlop and Galt away to Ballymote. Galt and his wife remained for three years at Ballymote and then went to Ballyshannon where she lived to upwards of 100 years old."

  7. Reporting his death, the Cork Constitution stated that he "had served with his brother in the Army of Napoleon" (which he didn't). William Drummond Dunlop died at Monasterboice, 08/03/1873.
