Alexander Wright, brother of pursuer William Wright, died without issue in 1747. His widow, Agnes Ellis, was entitled to an annuity and a sum of money; additionally, Alexander left a small heritable subject and about £200. Although William was Alexander’s heir at law, he decided not to claim these subjects while Agnes lived. Upon Agnes's death, her niece Mary Ellis took possession of the subjects, and William sued. He prevailed, leading to the question of how much interest Mary owed.
