Genetic Genealogist & Medical Doctor
Dr Tyrone Bowes
I am a trained scientist with a First-Class Hon's Degree in Biotechnology and a PhD in Neuroimmunology. I spent over 20 years in Academic and Commercial research labs in the UK and Ireland before commencing Irish Origenes (2010). I added the Scottish and English Origenes websites in 2012 and Origenes maps website in 2021. I spent 12 years writing commercial ancestral Y-DNA, Autosomal, mtDNA, and non-DNA Surname reports. My customers include Presidents, Academics, Philanthropists, and Celebrities. In 2024 I used the data from the Irish and Scottish Y-DNA Case studies to reconstruct the human history of Ireland and Scotland! What was revealed is a fascinating story of conquest, settlement and assimilation.
