I hope the following information helps. Your Roger o’donnell Born 1860 may not match the one I have but I’m sure the families are related. Patrick Troy in Curraghkilbran,galbally had two leases one each for lots 3 and 4 from about 1826. In 1865 lot 3 was divided and John Daly took the lease for 17 of the 19 acres, with Patrick retaining 2 acres as lot 4A. Patrick died in 1876. The holders of lots 4A and 4B (about 8 acres I think) are then shown As:
1877 representative of Patrick troy then 1881 David Keane
1884 Michael O’Donnell
1911 Michael O’Donnell land act purchasing indicating he became the owner
1935 Rodger O’Donnell 1970 John McSweeney who inherited from an O’Donnell aunt . Mrs. McSweeney still lives there.
Next door to her is Tom Fraher. Next to Tom is Sarah McSweeney then the Daly land.
I hope this helps. Tania Sweeney see Irish central website for Adare conference for article on Troy land.
