Episode 5 of 5
A five part series of stories following family members who are reunited after separation through family circumstance, tragedy or conflict.
As well as hearing the emotional stories of people who have been searching for others for many years, we also hear the stories of the organisations who help them - including the Red Cross, Salvation Army and Missing Person's Bureau.
The internet has increased the possibility of finding people through social networking and other websites - such as a site set up recently by Missing Person's Bureau and featuring details of unidentified bodies.
The stories have a range of outcomes, not always happy.
Episode 5 (of 5): Haiti Family
As poor subsistence farmers in Haiti, parents Carnise and Dieuseul couldn't afford to look after their children properly. So they made the difficult decision to send them away to an orphanage with promises of a good education and better life. Little did they know their children would be mistreated and exploited by a pastor who has since been jailed for child trafficking and slavery. Their situation was further worsened by the 2010 Haiti earthquake - after which neither the children nor the parents knew each other's fate for two years. Now reunited, the family are just one case of many helped by the International Rescue Committee throughout the world.
