The death of Simon Wrigley's beloved grandmother ignited a fire in him to research his family history. What he traced was a family tree stretching back over hundreds of years, uncovering living relatives on his grandfather's side that he never knew he had. Simon and his partner make the 4,000-mile trip from their home in Israel to Simon's birthplace on the Isle of Wight. There, they visit the grave of his grandfather, a war veteran who died before Simon was born, and they attend a family reunion with his recently discovered relatives in the hope of filling in even more blanks in the family history. And we meet Lynn Lewis, who was shocked to discover that her parents had had a baby boy together when they were just teenagers. Despite going on to marry and have more children, the couple had been forced to give this first baby up for adoption. Lynn became determined to find her brother Dave and, after years of searching, finally received an address from an adoption agency. Could this lead Lynn to the brother she was so desperate to find? And after all these years, would he even want to be found?
