Alexander Morison, Lord Prestongrange

He was the son of John Morison of Saughtonhall (1558–1615), a burgess and treasurer of the city of Edinburgh, and his wife, Katherine Preston, daughter of John Preston, Lord President of the Court of Session.

John Preston (his grandfather) had built Prestongrange, a fine mansion west of Prestonpans, and this house came to belong to Alexander through inheritance around 1600.

[2] He trained as a lawyer at the University of Edinburgh under Henry Charteris, graduating with an MA in 1598.

[3][4] In February 1626 he was elected a Senator of the College of Justice and took the title Lord Prestongrange.

Saughton Hall stood in 98 acres (40 ha) of ground and was demolished by Edinburgh Council in 1952 to make way for housing.
