abraham kinghorn and margaret mcnab

[JACKEROO]

is there any record of who these were, who were the parents of abraham kinghorn, he married margaret mcnab,
they had children william, james, ann and betsey or elizabeth, in sleat or strath inverness
is there any date for a death for abraham, he must have died before 1837, all but william came to australia, so abraham must have died before then.
any leads or help greatly appreciated, thanks
margaret was amcnab before marrying abraham kinghorn,
