Townland "Bal of Dookinelly (Calvy)" is smaller than this. Bellanasally wraps around it to the north and west.

What is (Calvy) anyway?

Is it possible that "Bal of Dookinnelly (Calvy)" is an exclave of "Dookinnelly (Calvy)".
"Ball" in irish can mean part of, but it is Bal. It's unlikely, just a thought.
