Glennon Y-DNA study beginning
The Y or male chromosome is passed unchanged from father to son to son etc.If you or a member of your family are a male named Glennon, you have the same Y-DNA as your Glennon ancestor. A group of 8 men named Glennon in the US and Ireland are starting a Y-DNA study to see if all Glennons are related or if the Glennon name sprang up about the same time in several different places in Ireland. To find out more, contact Clarke Glennon.
