Charles Lambart, 1st Earl of Cavan

Charles Lambart, 1st Earl of Cavan (c. March 1600 – 25 June 1660) was an Anglo-Irish Royalist soldier and peer.

[2] He had succeeded to his father's barony on 10 June 1618 but as this was a title in the Peerage of Ireland, he was not secluded from sitting in the House of Commons of England.

Lambart was Seneschal of Cavan and of Kells in 1627 and made a member of the Privy Council of Ireland.

Following the Irish Rebellion of 1641, he raised a regiment of 1,000 foot guards against the Roman Catholic rebels.

On 15 April 1647, Lambart was created Earl of Cavan and Viscount Kilcoursie in the Peerage of Ireland, in recognition of his loyalty to the Royalist cause.
