I can add a little info to a few of your possible listings. In particular the last two re the Wills of Mary Joughin als Kerruish and Thomas Kerruish.

The Mary Jouhgin alias Kerruish, born in 1733, was the wife of James Joughin. She died shortly after the birth of a daughter, Mary Joughin in 1751. This Mary married Daniel Lace, and their son John Lace, born 1779, has been written about as having fought at Trafalgar.

The first Mary, maiden name Kerruish, was the daughter of Thomas Kerruish, born 1706 who died in 1738, and mother Jane Casement. When Thomas died in 1738 Jane married Mark Joughin.

I have a webpage which is apparently naughty, let me know if you want full detail on all of these.
