Sorry, Halkett owned it all; £688 is the highest value of any property in the Parish.
The only other landowners were Adam Bruce, John Erskine, Adam Stobie, George Chalmers of Pittencrieff and Lord Yester who held the Mill.
The Fife valuations do not include small land holders or portioners - less than 20 roods/rods (about 5 acres).
I took another look at your description of the land and it states 50 falls which is less than 1/2 acre.
Large enough for a house, garden and shop and not much more. Or...a tenement all in Cairniehill (which is a village) and lays within the boundaries of the estate. If it didn't it would have been listed separately.
