Have started following twitter through MetroTwit, where you can pin specific hash tags, I came across a blog on the Jones surname which included an interesting history of the Jones name: http://jonessurnamedna.blogspot.com/2011/06/jones-surname-not-genetic-but-phonetic.html?spref=tw
In my Great-Grandfather Thomas John Jones' diary it has "Thos John Jones, the Jones being used by David in town for ten years used also by Thos Samuel & Hannah. Arrived in New York March 4th 1883". Without this little tidbit of information, I would have search Wales for years with no luck. I found it interesting that Thomas, his brothers & sister all appended the Jones to the John. He was known in later years as Dr. T. J. Jones, M.D.
