Baron Castlemaine

Baron Castlemaine, of Moydrum in the County of Westmeath, is a title in the Peerage of Ireland.

Handcock represented Athlone in Parliament and also served as Governor of County Westmeath.

In 1822 he was further honoured when he was made Viscount Castlemaine in the Peerage of Ireland, with remainder to the heirs male of his body.

On Lord Castlemaine's death, the viscountcy became extinct as he died childless, but he was succeeded in the barony according to the special remainder by his brother Richard, who became the second Baron.

His son, the third Baron, was also Member of Parliament for Athlone and sat in the House of Lords as an Irish representative peer from 1841 to 1869.
