According to family "history", the father, John Moore was on the Victory at Trafalger. There was indeed a private John Moore on that ship, but from what I gather was born around 1777, which would make him a relatively older father, but still possible I suppose, that or the one on the Victory was a grandfather. I am presuming that there must be this connection as it seems unlikely to me that the name of a private on the ship would have been known to all and sundry.
