I have had it confirmed that this photo was taken in Oatlands.

I don’t have many names but I recognise my dad J O O’Toole 3rd from the left at the back and 4th from left is Basil Gallagher. 2nd from the left in the middle row is Tom Byrne (The major) and then Jack Haughton followed by Pat Rochford. Four more along we have Frank Gallagher and 2nd from the right in the middle row is Paddy Reynolds.
