Find My Family is an Australian television documentary series airing on the Seven Network. The first two seasons were narrated and presented by actor Jack Thompson. From the third season onwards it did not have a presenter, instead being narrated by Sarah McIntyre. The series is based on an original Dutch format created by public network KRO, titled 'Spoorloos'. Find My Family reunites long-lost family members who have been separated for many reasons and circumstances. The absence of family members often leaves gaping holes in people's identities. These reunions attempt to fill those gaps by reconnecting family members. Host of seasons 1–2, Jack Thompson was adopted as a child and reunited with his father as an adult. He also traced his family's ancestry in an episode of the documentary series Who Do You Think You Are?. There is also an American version airing on ABC that began airing on 23 November 2009. The US version was produced by RDF USA.
