Earl of Aldborough, of the Palatinate of Upper Ormond, was a title in the Peerage of Ireland held by the Stratford family. It was created on 9 February 1777, along with the courtesy title of Viscount Amiens, for John Stratford, 1st Viscount Aldborough,[1][2] a descendant of the English Stratford family.[3] He had already been created Baron Baltinglass, of Baltinglass, in the County of Wicklow,[4] on 21 May 1763, and Viscount Aldborough, of the Palatinate of Upper Ormond,[5] on 22 July 1776.[2] These titles were also in the Peerage of Ireland. Three of his sons, the second, third and fourth Earls, all succeeded in the titles.[6] They became extinct on the death of the latter's grandson, the sixth Earl, in 1875.[7]
