Viscount Loftus is a title that has been created three times in the Peerage of Ireland for members of the Anglo-Irish Loftus family.[1]
The first creation was for Adam Loftus on 10 May 1622, who served as Lord Chancellor of Ireland in 1619. This title became extinct in 1725 upon the death of the third viscount, who had no male heir, despite having married three times.
The second creation was for Nicholas Loftus in 1756, a great-grandson of Adam and a member of the Irish House of Commons. Two of his sons were created earls as Earl of Ely, although both titles became extinct.
The third creation of the title was for Charles Loftus in 1789, who became Marquess of Ely in 1800.[2] This title is extant.
