Hello Averil,
I don't know whether this affects the argument one way or the other, but please don't forget that you got the descent wrong. The land went to John Looney directly from his parents [father's will] not to eldest son Daniel and then to Daniel's son John.
John Looney's 1770 will: "The sd. Daniel Looney & his wife …. and also agreeing to acquit and give up the half of Gob no Scoote w’ch he had in Settlement to his brother John Looney in lieu of Crow creen Lands at ye decease of the Survivor of us together with our other half of Gob no Scoote which I leave and bequeath to my Said Son John after the Decease of the longer liver of us…"
So the land went from father John d.1769 to his son John, not to son Daniel and then to Daniel's son - it clearly went to his brother - it couldn't be more specific.
