Ref: William Clague 1818-1893 married his first wife, Catherine Quine 1818-1859 in Santon.

Not sure if this helps , but I think you could eliminate the Glentraugh one

[Person 1] Catherine Quine b Santan 18 Sep 1818 married 19 AUG 1835 Cleave Kinely

[Person 1]
Will 1838
9 May 1838 John Quine of Glentraugh mentions wife Esther Quine, son John, William, James, daughter Jane, Christian, Esther, Elizabeth, Catherine now the wife of Cleave Kinley, I give and bequeath unto my daughter - missing info. [probably Margaret Quine]

Will 1845 Glentraugh
Esther Quine, [Esther Gick] 1845 of Santan, mother of James [of Douglas Druggist] John, Margt, Esther Quine, Ann and Elizth Quine minors , Catherine wife of Cleave Kinely, all of Santan and William Quine of Malew next of kin.

As in 1845 Catherine Quine daughter Esther Gick is refered to as Catherine wife of Cleave Kinely. It is more probable that she is not the same person who married William Clague in 1839

[from Ellan Vannin vol 1 #1 p11/16 Dec 1923, not sure if this is relevent but a coincidence on the farm and surname?]
Margaret Kinley, only daughter of Edward Kinley, of the Black Hill estate, Malew; and upon the death of her father and the remarriage of her mother she inherited this estate, which they farmed for a number of years before going to take over Glentraugh, which was a much larger farm.

[Person 2]
I have this on the other family, but a lot of my records are not validated and are based on the IGI
