Technically the 1659 map isn't very accurate as Brenagh, an variant form of Walsh, is recorded in the 1659 "census" as one of the principal Irish names in the parish of Achonry, Barony of Leyny. Thats why in the second map its so prominent in that area. It wasn't a case of to hell or to Connacht. Also Walsh was still the 2nd most common name in Killkenny in 1890
