Genetic Genealogy

Genetic Genealogy is my newest passion!

I have many years of experience with traditional genealogy research and have recently became interested in using DNA testing to help push back some of the genealogy dead ends we all seem to have an abundance of in our family trees. I have spent the past 18 months immersed in genetics education, completing four university level genetics courses as well as following online forums and blogs. We are on the frontier of this new discipline with major developments occurring almost weekly. Staying up-to-date with this fast developing field is challenging.
