O'Flanagan calls him "a nobleman of considerable abilities, who filled several offices connected with the Government of Ireland". He was also, like his father, determined to assert his family's traditional rights as Lords of Howth, and was sometimes accused of overstepping the law as a result. In 1468 he was charged with piracy, the particulars of the offence being that he has attacked a
Breton merchant ship off nearby
Lambay Island, pursuing it as far as
Drogheda, and seizing the
anchor. However, he was acquitted of the charge of
piracy. The notoriously vindictive session of the
Parliament of Ireland held at Drogheda in 1468 was largely devoted to destroying Desmond and his associates. Howth, however, was able to obtain an exemption from any acts of
forfeiture passed by Parliament, He was
High Sheriff of County Dublin in 1456, Chancellor of the Green Wax in 1468,
Chancellor of the Exchequer of Ireland in 1478 (the last two offices were often interchangeable), and Clerk of the
Court of Common Pleas (Ireland). Like his father, he played a key role in the defence of Dublin. He was ordered to erect a
tower at
Kilmainham bridge, and in 1467, was charged with organising the
militia. In 1474, he was chosen to be one of the thirteen Knights of the
Brotherhood of Saint George, a
standing army charged with defending
the Pale against invasion by neighbouring Gaelic clans, and with keeping the peace generally. == Family ==
