PR says John Kneen & Jane Camaish, Maughold. So it might be either Jane or both of them, I thought.
It was first written John Kirmeen but this was crossed out.
As I recall, there aren't Kneens or Camaishes in Michael at that time that fit either of these two. I hadn't thought of the widow for JC, though. Will investigate that possibility.
Interestingly, later one of the Ramsey-born grandchildren of this John Kneen ends up in Michael, so there is this vague connection that may mean something, or not.
