Each of the Monaghan-Monahan Surname DNA Project Pedigrees should identify the Earliest Ancestor and the researcher.   By correlating test results and pedigrees, each family can identify their genetic heritage and related families.

Each participant is asked to submit his paternal pedigree for the Monaghan-Monahan Surname DNA Project.  Please send your file to the project administrator via the link on the Project Home page.
