For those of us who research family history in the UK and Ireland from North America it's frustrating to learn about expert presentations being given back there, and having no access. Now there is one channel opening up, and it's free. The National Archives at Kew has placed online a series of talks, some of which are relevant to family history, in the form of podcasts. "Tracing births and deaths on board British and colonial-registered merchant ships " was given last December by Chris Watts of TNA. The link for this and other TNA podcasts is here.
