Autosomal DNA (atDNA) testing examines over 700,000 DNA markers on your chromosomes and allows you to compare your DNA with that of other people. If you are genetically related, you come up as a match to each other. There are now more than 3 million people in the various databases and this is helping people to reconnect with long lost cousins, many of whom have genealogical evidence that is helping other people break through their Brick Walls. This presentation looks at how you can use atDNA in your own family tree research, how to interpret your results, and how to use them to best effect.

Maurice Gleeson, a psychiatrist and pharmaceutical physician by day and a genetic genealogist by night, is administrator for the Gleason/Gleeson, Spearin, Farrell, Irish Caribbean DNA and WW1 Missing Legacy projects. He has helped organise the DNA Lectures for “Genetic Genealogy Ireland” in Dublin and “Who Do You Think You Are” in the UK since 2012, as well as given talks all over Ireland and internationally. His YouTube videos on genetic genealogy are very popular and he was voted “Genetic Genealogist of the Year 2015” by the SurnameDNA Journal.

These lectures were sponsored by FTDNA (FamilyTreeDNA) and organised by volunteers from ISOGG (International Society of Genetic Genealogy).
