The DILLON surname Y-DNA project welcomes all variations of this surname as participants. Y-DNA testing is a tool which can be used to prove or disprove traditional genealogical research, determine relationships and may help provide direction for further research. The goal of the DILLON project is to help all DILLONs (or variant surnames) to find common ancestors and establish connections among the various families. Click on the ABOUT THIS GROUP tab and then select the NEWS tab to view a summary of the earliest known ancestors of project participants. You can also keep up to date with the project through our Facebook page and blog: www.facebook.com/dillondnaproject/ www.dillondna.blogspot.co.uk
