kronkold is a place (Cronk Ould) - if you look at registers usually added as a distinguishing mark befor 1762 when wife's full name was given.

I was asked to look at will of Margt quayle als cowley - obviously wrong one - she was wife of phinlo quayle m Bal 1760-12-02 - thus there might well be another Margt Quayle's will worth looking at.

I was also asked to look at a number of Wm Quayle wills - this was the first and again I suspect a wrong family.

I'm not sure how much genealogical research you have done but dead ends/mistaken identities are quite common - I'm just reporting back - maybe Sue has more ideas
