Can anyone identify Isabel Skillicorn who married Thomas Cowin at Lonan July 28, 1730?

Is this Thomas Cowin's will: 1746 film 0106218: Children Ann wife of Thos Christian, Mary, John, Jane.

I am looking for Isabel Skillicorn, widow of John Skillicorn who died at Lonan in 1729. I have no evidence that she remarried, but I think she was a fairly young woman when John died.

John Skillicorn's decree in 1729 names his "only son John" (no wife) and states John is of age.

I think I have identified Isabel, John Skillicorn's wife as Isabel Christian, but have no parents for her.

Interestingly, John Skillicorn's sister Isabel married Thomas Christian. It took me a long time to figure out that there were two Isabel Skillicorn-Christians!
