A Celtic group, predominately Protestant, that is undoubtedly most prevalent in parts of the South. Thomas Jefferson was a Welshman, and undoubtedly the most famous person of that ancestry. I only met one person of this group in 30 plus years of living in New England. Jones, one of the most common names in the English speaking world, is of Welsh origin. The common name Walsh is an Irish one, but refers to an Irishman of Welsh roots from way back.
