That much is known. Where exactly they stood is not. It is the kind of absence that quietly defines a great deal of early modern Irish domestic history, where the physical evidence has long since vanished and the paper trail is thin and indirect.

The principal documentary trace comes from the Hearth Money Roll for County Dublin, compiled in 1664. The Hearth Money Roll was a taxation record introduced under Charles II, in which households were assessed and charged a levy of two shillings for each fireplace they possessed. As a result, the rolls offer one of the earliest systematic glimpses of domestic settlement patterns across Ireland, recording not grand estates but ordinary inhabited dwellings. The 1664 roll refers to dwellings in a place recorded as Little Clanshogh, an earlier spelling of what is now Clonshagh, a townland in the Coolock area of north County Dublin. The reference was identified and cited by Cary between 1930 and 1933, and the site was later compiled as a record by Geraldine Stout, uploaded to the national monuments database in August 2011. No precise location for the structures has been established.

For a visitor, there is no marker, no ruin, and no obvious focal point to seek out. Clonshagh today is absorbed into the suburban fabric of north Dublin, close to Dublin Airport and the surrounding residential and commercial development that has transformed this part of the county over the past several decades. The value of knowing about this record lies less in any physical experience of the site and more in what it illustrates about the landscape beneath contemporary Dublin, a layer of early modern settlement that has been built over, forgotten, and only occasionally surfaces through documents like the Hearth Money Rolls. If you find yourself in the area, the townland boundary itself is the only geography that connects the present ground to that 1664 entry, and even that connection is approximate.
