Lillias,
Glencrosh was one of 20 principal farms of Ingleston held by the Laird of Ingleston and who he is depends on the era. Properties changed hands frequently. I do have a copy of the 1790 Directory of Land Ownership and it appears John Grierson of Urr is the current Laird and a Mr. James Crack is noted as the previous owner.
I did see one John Gibson, the younger of Ingleston who was a Covenanter and killed in 1680 along with John Gibson of Auchencheyne and a Robert Grierson of Glencrosh.
A Gibson did own Glencrosh post 1800 and a Mrs. Gibson owned it in 1855 but it was occupied by Robert McMillan of Holms and as I see no Gibson on the fam in 1841 I suspect she lived elsewhere.
