Hi; Only my opinion, but I think "Jno" is simply to be taken as what it is -- an abbreviated form of a name, whether John or Jonathan. I have seen it for both, by the way. Just like "Wm" is William, and "Edw." might be either Edward or Edwin. Just someone's idea of shortening a writing chore. There would have to be other documentation to verify what the person's name really was. Ann Bergelt Florida
