Ah, I see. That's awkward (although that's why I asked OP when the christening was, in case of such conflict). I thought we were onto a good lead here. That said, maybe the stories about him have got muddled with this other man? Does OP know he was alive for the christening, or perhaps he gave an earlier gift after the marriage "for the christening of your first little one", especially if he knew he was dying? Pulling at straws there perhaps. Maybe given by the widow or another close relative, in the "he'd want you to have it" kind of way?
