The harrowing plight of child migrants such as Hennessey is examined in the film Sunshine and Oranges, which opened on Thursday. It focuses on a British social worker, Margaret Humphreys, and her work to blow the whistle on the child migration schemes and help the victims find their families.

Our Library currently does not have a copy of this book or Empty Cradles the previous title- I have suggested it be purchased. It can be obtained from Book Depository UK for $11 approx. dollars postage free. 380 pages -- the books covers very much more than the film and is a must read account.

Oranges and Sunshine recounts the true story of a Nottingham social worker who has dedicated her life to reuniting the thousands of child migrants sent from the UK to Australia between the 1940s and 60s with the parents and families they were told did not exist.
Based on her best-selling book Empty Cradles, Oranges and Sunshine follows Margaret Humphreys (played by Emily Watson) as she battles to bring emotional closure and justice to those who suffered at the hands of those institutions (governments, Christian Brothers, "charitable organisations") charged with their care.http://www.childmigrantstrust.com/
