Baron Trevor

The final creation of the title came in the Peerage of the United Kingdom in 1880.

Lord Edwin Hill, third son of Arthur Hill, 3rd Marquess of Downshire and for many years Member of Parliament for County Down, had succeeded to the estates of his kinsman Arthur Hill-Trevor, 3rd Viscount Dungannon (see the Viscount Dungannon) in 1862 and had assumed by Royal licence the additional surname of Trevor.

In 1880 he was raised to the peerage as Baron Trevor, of Brynkinalt in the County of Denbigh.

As of 2017[update] the title is held by the latter's grandson, the fifth Baron, who succeeded his father in 1997.

The family estate is Brynkinalt (Welsh: Bryncunallt), near Chirk, Wrexham County Borough, in Wales.
