Leaving to one side the work of the Ordnance Survey in the 1830s, the work of Petrie at Clonmacnois, and that of Cooke at Birr in 1826 and 1875, the references to and work done or written up on the historical sites of north Offaly in the nineteenth century are hard to come by. Fr Cogan published historical material on the Offaly parishes in the diocese of Meath in his three-volume work, 1862-1870; Thomas Stanley corresponded with the Royal Society of Antiquaries (RSAI) in 1869 in regard to the nine-hole stone or bullaun at the Meelaghans while Stanley Coote contributed an illustration of Ballycowan Castle for the Memorials of the Dead – a published record from the 1880s to the 1930s of selected tombstone inscriptions in Ireland and in County Offaly.
