Maurice is a psychiatrist, a pharmaceutical physician, & a genetic genealogist. He did his first DNA test in 2008 and since then has used DNA to good effect in his own family tree research, finding relatives in Australia whose ancestors had left Ireland in 1886, and tracing one line of his family back to the 1600's in Limerick. He is now Project Administrator for the Spearin, Farrell, and Gleason Surname Projects and runs several special interest projects, including the iCARA project, which aims to help people with Caribbean ancestry and Irish surnames find their ancestral homelands and even distant cousins living today. Maurice organises Genetic Genealogy Ireland and speaks about DNA and genealogy at international and national meetings.
