Hi again NW,
Remember I confirmed that Mary Carnegie, 1st daughter of Thomas, 4th Esq of Craigo, married George MacPherson Grant, NOT John Alexander, so not the same Mary Carnegie John married. Well I have just recently discovered that the George Bertram MacPherson Grant family was the proprietor of the Craigo Estates which would include East Hill of Craigo that was farmed by Alex. Alexander and May Niddrie. Appears the Niddries were there from at least the beginning of the 19th century. Craigo Estates also included the Beattie/Alexander house in N Craigo (recently renovated and called Springbank Cottage).
