|I am researching the Welch family from Ireland. Specifically the forebear of Thomas Welch (or Welsh) and wife Mary Ann Kavanaugh (again spelled - Cavana - Kavanah and Kavanagh). The area that is most closely associated with Welshes, where they have given their name to the Walsh Mountains in Co. Kilkenny. The earliest beleived to have been called is said to have been Haylen Brenach, alias Walsh, son of "Philip the Welshman", in 1172.|
The Walshes of the southern-eastern part of Ireland are mostly decended from the Philip mentioned above and from his brother David; and the leading members of this family established themselves as landed gentry at Castlehowel (Co. Kilkenny), at Ballykileavan (Co. Leix), at Ballyrichmore (Co. Waterford) and also at Bray and Carrickmines near Dublin.
The pedigree of the Tirawley (Mayo) Walshes was compiled by Lawrence Walsh in 1588. He states that they are decended from Walynus, a Welshman who caqme to Ireland with Maurice Fitzgerald in 1169 and that this man's brother Barrett was the progenitor of Barretts of Tirawley (q.v.p. 5I supra).
