I have tried to nail down the information on Patrick McCosker of Agharonan (1860) but I am having difficulty in locating the farm at that time. I know that it was Samuel Vesey property (of Derrybard House in Seskinore) but not where the property was on the Griffith's Valuation. I understand that the numbers in the valuation were only the sequential listing of the occupiers and not the address of that occupier. So, it does not compute that once you have the number of the property you can follow it looking at the land records. You actually have to have the locus of the property as shown on the map at the time. The problem is that http://griffiths.askaboutireland.ie/gv4/gv_family_search_form.php does not have the original material on Patrick McCosker's property, only a reference that is transcribed. Without that what does it mean when you have Sheet 51 (which I do know, having the whole sheet) and then the "position" and/or "map reference?" I have three numbers: 34 (which I believe may be the property in question), 39 (which does not appear on the Griffith's map that appears on Ask about Ireland) and 7. Until recently, I thought that the numbers related to the addresses and not the order that the census taker (or whatever he was at the time) listed the occupiers. That really caused me a lot of problems tracking down my McCarroll's of Corkhill but learning of the meaning of the order of numbers clarified the situation. But it did nothing to bring back the old homestead which I was present for its tearing down. Regards, Jim Carroll
