I've sent this over from something I put on the Nir-Down list in case anyone is interested. We were discussing the name Rostrevor and Welsh influences in Ireland Edward Trevor went over to Ireland with Edward Blayney of Montgomeryshire as a Captain after the Battle of the Yellow Ford in 1598.(short article at http://en.wikipedia.org/wiki/Battle_of_the_Yellow_Ford). Briefly - he married Rose, his second wife,daughter of James Ussher, archbishop of Armagh. He settled in County Down , naming his estate there Rostrevor. One of his sons Mark -by this second marriage to Rose became 1st viscount Dungannon and Baron Trevor of Rostrevor in 1662. The Trevors brought a strong contingent of Welsh settlers with them who spread out in the surrounding areas. There were other Welsh families from Denbighshire and Flintshire who followed the Trevors putting their stamp on Irish surnames and placenames. The Trevor family (1662-1862) were the Viscounts Dungannon The Brynkinalt Manuscripts (Irish Estates) cover the period 1612 -1750 and refer to Counties Antrim, Armagh, Cavan, Cork, Donegal, Down and Monaghan; rentals and accounts,1663-1909 .A student at an Irish university has completed his PhD on the Trevors of Rostrevor. I am reading it at present. The Trevor Mss are a mine of information on the 'happenings' of the family and Irish , and Anglo-Welsh settlement I include a section from the will of Sir Edward for anyone who is interested. It is a 'copy of a copy' It may be of interest for names and places. Sir Edward died in 1642 after a period of imprisonment in Newry . Proved in the Pregoative Court in Dublin 1649 - Ref Brynkynallt Mss DD.BK. 1.47 'In the name of God Amen.
