Greenhalgh, Greenall, Greenhill, Greenwell, Greenhall, Grannell, Grunnell and all other variants, are included in this project. With a variety of different roots, the surnames focused on in this project trace back to roots in both Ireland, and England. Those of Irish descent likely descend from an ancestor with the surname "Ó'Grianáin", which was anglicized over time to the surnames: Green, Greene, Greenan, Grennan, amongst others. (See Greenan and Greening DNA Projects) Those of English descent appear to be derived from medieval British locational or topographical names meaning one of Green Hill, Green Hollow/Hole or Green land by the water. Anglicized forms include: Greenhalgh, Greenall, Greenhill, Greenwell, Greenhall, Grannell, or Grunnell, amongst others. Throughout the ages the names have changed in both spelling and pronunciation. The main goals of the project are to help participants solve longstanding genealogical problems and to determine which lines and surnames are related. Participation is open to anyone with known or speculative paternal roots relating to any of these surnames or variants!
