(details deleted... was looking at the incorrect townland... will have another look...)
I'm not sure that the property boundaries on the linked map agree with the Griffith's details. The valuation page includes properties numbered 1 to 35 with sub-division (a, b, c, etc), whereas the map shows divisions numbered 1 to 73.
The sum of all the property areas on the valuation (1099 acres) agrees with the caption on the map and on the townland database, but the sizes of the individual property sizes dont seem to match this. e.g. properties 22,23 and 24 are about the same size and yet they are indicated as 32, 103 and 12 acres on the valuation..
not sure if I'm missing something here...but will look a bit further..
