The filmed records of Griffith's Valuations (Householder's Index) contains name of the head of household of each occupier of land, the name of the immediate lessor, the ordinance survey reference number of the townland, the map reference letter and number of the plots in the townland for each family, a description of the property (house, office, garden or land or bog etc.), acreage in acres, rods and perches, annual value in pounds of land and of buildings separately stated, and total value of the property. The Valuation Office in Dublin will provide copies of maps of each townland in Griffith's. I do not know the cost. These maps will clearly show the plots divided into lettered and numbered units. I obtained mine from the public library at Dungarvan in Waterford. Remember that the Waterford survey was done early, around 1852, just after the worst of the Famine. You may find other names listed as neighbors to your ancestor, or the entry that you think may be your ancestor. You may find odd names that have appeared as sponsors in Baptism to the children of your ancestor, thus confirming the likelihood that you have found the right family. Sometimes, if the names in a townland are the same or there are many of the same surname, the survey will include in parenthesis the name of the father of the listed person, i.e. Pat'k (Michael) Hughes, meaning Patrick, the son of Michael Hughes. As an example, I found what I believed to be my great grandfather listed in the townland of Glencairn in the Parish of Lismore and Mocollop. Listed a few doors away was John Quirke. David Quirke was godfather to Catherine English born to Michael English and Mary Sullivan 22 Aug 1829. This is too close a coincidence to be ignored. In the townland right next to Glencairn, a family named Bocedy resided. My great grandmother Catherine Mary English's sister, Ellen married Daniel Bocedy in 1841. Wheels within wheels. I also found that the precise property for which Michael English was being taxed, parcel 4 (e). This parcel turned out to be one of a row of estate cottages which each had a front garden and two rooms. Sort of like a stable for people, poor dears! No wonder they all, every one of them, took off for America. In answer to your question, it depends on how obsessive you are about subtle details. Sheila MacAvoy Block
