In the US & Canada, when one thinks of WDYTYA, you think of the US TV show. In the UK, besides there being a TV show, there is also an associated conference held called Who Do You Think You Are? Live
Since many of us have not nor will not ever attend this conference, it’s great that select presentation handouts are available online.
This link is to an archive of WDYTYA? Live Speakers’ Handouts (created by the Society of Genealogists) for conferences held in 2014 & 2015. These are FREE to access and it’s a great collection of topics and not just about UK research!
