These lectures are sponsored by FamilyTreeDNA and organised by volunteers from ISOGG (International Society of Genetic Genealogy).
The video presentations from GGI2017 Dublin will be uploaded AFTER the Belfast videos (as the sound needs to be optimised given the background noise in the auditorium which was unfortunately beyond our control).
