American Terry Byng has been reunited with the Portsmouth family he never knew about following a chance discovery on Facebook.
Mr Byng's father Jack went to the US during World War II where he met and married a woman called Nancy.
A few years later Jack left Nancy and returned to Portsmouth. She was pregnant with his son, but it is believed that he did not know.
His British family never learnt he had a son either, even after his death.
BBC Inside Out South is on Monday, 5 November at 19:30 GMT and nationwide on the iPlayer thereafter.
