Earl Roberts, of Kandahar in Afghanistan and Pretoria in the Transvaal Colony and of the City of Waterford, was a title in the Peerage of the United Kingdom.
He had already been created Baron Roberts, of Kandahar in Afghanistan, and of the City of Waterford, in 1892, and was made Viscount St Pierre at the same time as he was given the earldom.
The barony was created with normal remainder to the heirs male of his body while the viscountcy and earldom were created with special remainders to his daughters and the heirs male of their bodies, as his sons had already predeceased him.
He was succeeded in the viscountcy and earldom according to the special remainders by his eldest daughter, the second Countess.
The latter’s son and only child Lieutenant Frederick Roberts Alexander Lewin was killed in action in the Second World War and consequently the viscountcy and earldom became extinct on the third Countess’s death in 1955.
