Fifth son of William, fifth Lord Cranstoun. Disowned his marriage in 1746 but wife insisted on its lawfulness. 
Whilst in England, Cranstoun fell in love with Mary Blandy whose father objected to the relationship citing Cranstoun's Scottish marriage. 
Blandy poisoned her father and was executed in 1752. Cranstoun was said to have sent the arsenic from Scotland, although there was no concrete evidence to link him to the murder. 
Died 1752 in Flanders.
