Erin, The Town of Lismore is in the County Waterford. The organization of Irish records goes from the largest, County, to Barony to Civil Parish to Townland as the smallest political entity. Within the townlands are the specific farms. "Irish Records" by James G. Ryan is a good start. The Townlands of Curraheen North and Curraheen South are in the Civil Parish of Lismore & Mocollop. You are lucky as the County Waterford is part of the ancient lands of the Decies (pronounced Desha). There is great literature and tradition associated with this place. My people are from the same part of Waterford. The Civil Parish of Lismore & Mocollop is in the north-west corner of County Waterford. Within that Civil Parish is the Town of Lismore, seat of the Duke of Devonshire (to this day!). There is a Bartholomew Corcoran listed as a tenant in Curraheen South in Griffith's Valuation of Tenements, the Householder's List which is essentially the only Census substitute for Ireland in the 19th Century. There are no other Corcorans listed in either Curraheen North or Curraheen South. On my Discovery Series #81 map, Curraheen South is just outside of the Town of Tallow on the north bank of the River Bride. There is a little mountain between it and Curraheen North. It must be pretty country. The Waterford Heritage Center in the City of Waterford has all the Catholic records, if your ancestor was RC. They can be contacted through the Internet. They are pretty good, but cost money. But you could probably do a lot yourself with the Civil Registration of Births and Marriages which started in Ireland in 1864. Griffith's indicates Bartholomew Corcoran was a tenant. His landlord was the Duke of Devonshire. The family may have owned land by 1877. The Waterford County Library has a free list of all Deaths and Marriages in the County dating from 1864. Google will get you there. The Library also has Griffith's for the County, including the Ordinance Survey maps created at the time of Griffith's Valuations which was early for Waterford, 1852. Good Luck Sheila MacAvoy Block
