Down (called by him Rostrevor) and helping in the plantation of Ulster. He was pensioned (c. 1605), knighted in Ireland by the lord deputy (5 November 1617), and put on the Irish privy council (c. 1623) by James I, and represented Newtown (Co. Down) in the Parliament of 1634, but fell into the hands of the rebels in November 1641, dying soon after his release in the following May.

In 1619 he had built (traditionally from designs by Inigo Jones) the present mansion of Brynkynallt, later enlarged and 'gothicized' by the 2nd viscount Dungannon (1763 - 1837).

Sir Edward Trevor (c. 1580–1642) was the founder of the fortunes of the Trevor dynasty, a major family of Denbighshire. He was the son of Robert Trevor and Katherine ap Llewellyn. His first wife was Anne Balle, daughter of Nicholas Balle.

While on military service in Ireland, in 1612 Edward Trevor married as his second wife Rose, a daughter of Henry Ussher, Archbishop of Armagh and his second wife Mary Smith, and acquired an estate in County Down which was renamed Rostrevor, incorporating his own name. He was knighted in 1617 and built the mansion of Brynkynallt on his estates at Chirk in 1619.

In 1622 he was appointed High Sheriff of Denbighshire and in 1634 was elected Member of Parliament for Newtown, Montgomeryshire.

In 1641 Trevor was captured and imprisoned by Irish rebels, and he died in captivity.
