Thanks so much for the above information on the Dropes. I suspect they were an English family members of which went to ireland to study, as merchants and/or as English planters sometime in the 1600s. The Drope family name comes up on internet searches in London, elsewhere in England, Europe and America. Below is a bit more information I have gathered on the Dropes.
For example, in 1474 the ‘Maior’ of London was Sir Robert Drope, Draper, son of John Drope of St Edes in Huntingdonshire.[i] In 1567 a John Drope is mentioned in records of the Corporation of Lincoln: 1567, June 12.—John Drope, B.A., to be usher of the free school. f. 18b.[ii]A John Drope, who died in 1629, is commemorated on an altar tomb in the Norbury Parish church, Derbyshire.[iii] Dropes appear in Irish records around the 1630s and in County Cavan, Ireland records from the early 1700s.
A John Drope of Cootehill, County Cavan made a will on 11 November 1774. (See Index to the Prerogative Willis of Ireland (Vicars), referred to on the Fermanagh Gold website at http://www.fermanagh-gold.com/search1?term=Cootehill accessed on 13 April 2012.

The surname Drope occurs as a second name in a quite a few of the members of the Australian McIllree family. Our progenitor, Henry McIllree (1824-1882) who arrived in Australia c. 1849, was the son of John Drope McIllree (c. 1782-11.8.1855) of Belturbet, County Cavan who inherited lands around Belturbet from his grandfather, John Drope. John Drope McIllree's wife was Margaret Quigley (c. 1783-7.1.1846). They had c. 14 children, of whom Henry was the youngest son. The McIllrees have connections also to Ballyhaise through Frances Drope, only daughter of John Drope and Anne Wiggins, who married Robert McIllree c. 1767. As mentioned in the earlier email, he died in Ireland on 23.8.1785. His will, unfortunately, is lost. Later John Henry McIllree (28.2.1849-17.5.1925), a son of one of John and Margaret McIllree's children, another John Drope McIllree (1812-26.4.1894), married Caroline Elizabeth Humphreys (22.11.1854-12.12.1930) of Ballyhaise House, Ballyhaise, County Cavan. The Drope family name crops up as a second name in quite a few of the Australian McIllrees.
