I little side note clarification is that the maps at Irish Times 'Irish Ancestors' site depict the later Griffith's Valuation (1847-64) distribution as opposed to the Tithe Applotments, which I think were sketchier. The GV did include Dublin. If you search Culledon here you'll find them in Kildare and a Culloden landlord in Dublin. http://www.askaboutireland.ie/griffith-valuation/ Martha Guild #5048
