Bass Maii MCCCXI". Sir John de Congaltoun of that Ilk appears to be in possession as laird just a few years later when he recorded a mortification dated December 13, 1314. The elder branch of the family succeeded through heiresses to the estates of Hepburn of Keith, in Humbie parish, and Riccart of Riccarton, in Kincardineshire. Robert Hepburn Congalton of Keith and Congalton, the 18th generation of the family, sold Congalton to his brother who became Charles Congalton of that Ilk (died January 1742) and in 1702 had married Janet Lauder (1671–1751), daughter of Sir John Lauder, Lord Fountainhall. Their son William Congalton of that Ilk (died 27 October 1753), who married secondly Mary Bethune (died 1751), daughter of David Bethune, 17th of Balfour, had ten children of whom only three married. The eldest son Charles Congalton (1736-1768), a Captain in the Royal Navy, in 1762 married Anne Elliot, daughter of Sir Gilbert Elliot, 2nd Baronet, of Minto and their two sons inherited their grandmother's estate of Balfour in Fife but did not marry (their sister Eleanor married Colonel John Drinkwater Bethune). A younger son Andrew Congalton (1749-1823), also a Captain in the Royal Navy, had a son Charles Congalton who died unmarried in 1827, so ending the male line. Islands Three islands, Fidra, Ibris, and the Lamb, belong to the parish of Dirleton. Fidra is the largest, directly opposite the village, and a mile from the shore. Upon it there was once the castle of Tarbet, a possession of the Congalton family. There was also here St. Nicholas's Priory, dating from 1165, the ruins of which still exist. The monks had a ferry from the island to the mainland, from which the farm of Ferrygate takes its name. Elbottle A Saxon word signifying "the old dwelling", Elbottle is also within Dirleton parish. Near Archerfield House there was a convent of Cistercian nuns, probably in connection with the large Cistercian nunnery at North Berwick. The Lauder family held lands here also. James Lauder (d. 1631), a great-great-grandson of Robert Lauder of The Bass (d. June 1576) held three husbandlands (78 acres) plus in Elbottle. His sister Alison was wife to the Minister at Gullane, the Reverend Andrew McGhie.
