my grandmother had a brief relationship with a charles warner aboard the uss trout submarine in 1958 whilst he was docked in london, her name was maureen and my mother (karen) was the result, he knew of my mothers birth but my grandmother moved without leaving him contact details (no fault on his part) I'm looking for any info on this man for family history and possible contact as he is unknowingly my grandfather and has 3 great-grandchildren all of which he will be unaware of
