Agreed with the the fact that the currently mapped north of "Bal of Dookinelly (Calvy)" should belong to "Bellanasally" instead. The proper boundary isn't to hard to spot on GSGS.

"Dookinelly (Calvy)"'s size is 1947 acres in OSM, which is close enough from GSGS's listed 1937 acres, so I think it's 2 distinct TDs, not one disjoint TD.

Plenty of TDs have "(some name)" appended to them, I've been told that some TDs have been split after they were defined, to match the landowner's name. So probably the Griffith valuation defined only "Bal of Dookinelly" and "Dookinelly", and later the second TD got split between the Calvy and the Thulis families.
