Genealogy and social media

Family histories are often the starting point for filmmakers like Gaylene Preston in the film Home by Christmas - not to mention historical novellists like Stephanie Johnson and Jack Lazenby. It's Family History Month, so family history research is being discussed and promoted around the country. Lynn Freeman looks at one of the big issues being talked about - social media, and the pros and cons of using it to track down relatives and fellow genealogists.She's joined by genealogists Donna Bridgeman and Lisa Durrant.
