I've just come across this thread.
Edith Mary Leslie Cunningham was a relative of mine. She was born in Belfast on 30 May 1880, only child of Thomas Cunningham (died 1 August 1895), Deputy Clerk of the Peace for County Antrim, and his wife Araminta Erskine Leslie (died 17 July 1927).
Araminta was the only daughter of William Leslie JP (1814-5 June 1880), manager of the Provincial Bank in Cootehill, Co Cavan, and High Sheriff of Cavan in 1875, and his wife Mary Erskine (d 1877), daughter of Moutray Erskine and Elizabeth Jane Wilson-Slator and widow of Henry Wilton. Araminta had one brother, William Moutray Leslie (died 19 November 1899), High Sheriff of Cavan in 1881 and a major in the Cavan Militia.
William Leslie was born in Rothes, Moray, son of William Leslie, mason, and Jean Slorach. I have 4 more generations of his Leslie ancestors in my database.
