My apologies - sent you a reply some time ago but checking this has shown it vanished into the ether somewhere.
My answer is no - I have never come across anyone with the name Le Noury (what a lovely name, too!).
My own experience suggests that ,especially in this case, there are many possible variable spellings and this may be the route to try.
There are several Morton wills available on line on the PRONI website. Let me know if I can help in any other way.
