William Brabazon, 1st Earl of Meath (c.1580 – 18 December 1651) was an Anglo-Irish peer.
[1] Brabazon was descended from an English family that was seated in Leicestershire from the reign of Henry III, and came to Ireland in the 1530s.
His grandfather, also William Brabazon, had served as Vice-Treasurer of Ireland for 23 years and the family acquired large estates there.
[4] In 1631 at Kilruddery House (which is still the family home) he hosted the marriage of his widowed sister Elizabeth to Sir John Bramston, the Lord Chief Justice of England (a belated love marriage which their father had forbidden many years earlier, but of which her brother evidently approved).
In 1644, at the height of the Wars of the Three Kingdoms, Brabazon was sent by the Irish Parliament to the Royalist court at Oxford to consult with Charles I.
