From the dates, the marriage was clearly a matter of urgency or rather 'too late'! Perhaps the family hushed up the whole affair. I see only one person it could be, if just the marriage and daughters were suppressed. If your John was left out of the family record completely then of course I have no way to find him!
I'd be very interested to know what your interest in this is (are you a descendant) and whether you have any other info about any of the parties; or whether I can give you any useful info, though this seems unlikely at the moment.
Actually I see on further search that at least 4 boys, names unknown, lived in the previous generation but have left no record of their further existence and your John may be an offspring from one of these or of a similar shoot. V difficult.
