Thanks for the additional info, actually The map from the 1920s looks like the current shed is located where the church would have stood, perhaps it was built from the remnants of the old church or is part of it, I hadn't noticed the chimney before.
As the church was only demolished in the early 1960s im sure there will still be those alive who remember it.
By the way my McCorkell ancestors lived in the adjacent townland, Ballyrattan.
Thanks again
Joe
