Hi Robert. Those numbers you can see, that you describe as being apparently located in radom places on the map, are the numbers given to each plot of land, occupied by landholders (tenants) - they refer to the 1857 Griffith's Valuation. The Griffith's Valuation details the plots, the landholders, the landlord, a description of the property held (house, outbuildings land) and the acreage, as well as the valuation. The later cancelled valuation books are a genealogy tool in that if you can locate an ancestor in the valuation, you can then trace the occupation of that plot through to the 1950s and beyond...........notes are made when a name change occurs, usually indicating the death or emigration of the landholder, and the name is usually replaced by a close relative as well. Hope that helps!
