It was created on 28 August 1799 for Micharl Smith, subsequently Master of the Rolls in Ireland. Smith married Maryanne Cusack. Their son, the second Baronet, assumed the additional surname of Cusack. He served as Solicitor-General for Ireland between 1800 and 1801. The title became extinct on the death of the sixth Baronet in 1970.
