The castle you want, in the townland of Milltown, is located at 876 448, along the eastern bank of the Ballyglass River. There is a bottom-of-the-line "road" (classed as "Other roads" on the map legend) - being Irish, you know what that means - which leads close to the castle, but stops on the other side of the river. For me, I'd try that first and hope that the stream is as shallow and fordable as it appears. Much of the stream has been straightened by man, so it may be more of a drainage canal than a flowing stream. In any case, if you have to go back, you can access the castle from the road to the east...and walk a half-mile or so. I haven't been there, although I was at the church in Commeen townland less than a mile NE in 2000. I don't have any information on the castle or townland, beyond a short attempt at a Google search (I'm sure you have done that). I did find, under a hit with -The Laigin - in the heading, the sentence "The Clann Uadach or O’Fallons (O Fallamhain) were lords of a territory in the barony of Athlone which comprised the parishes of Camma and Dysart, in the south of what is now County Roscommon. The ruins of their castle are at Milltown, in the parish of Dysart." I'd guess you've seen this before. I went through the Ordnance Survey letters of 1837 for Dysart and Taghboy civil parishes, but J. O'D. doesn't mention either of them. O'Donovan gets involved in early genealogies (as usual) for these parishes, but doesn't mention any names which would seem possible to construe as Fallon. Roscommon is a tough county for me to research as there is not yet an Archaeological Inventory published for the county, and I can't find a good history of Elphin Diocese - which covers much of the county. And all of the good stuff is in Dublin......which I never visit on my regular Irish trips <gr>. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Pete Schermerhorn, in the glorious Berkshire hills of western Massachusetts
