Welsh genealogy and the surname JONES can not usually be separated. The following is a summary table of the first who are recorded as taking the surname JONES. They are show by Welsh county and the dates that they were first recorded in the English legal records of the day. The table is a figure taken from my blog called "The Jones Surname" [ thejonessurname.blogspot.com ]. This blog discusses everything you wanted to know about the JONES surname but were afraid to ask.
The date of each post, which presents a little more about each JONES for the Welsh county listed, is shown above. The documentation of each JONES is given in the post. I thought this might be an interesting topic for those who have been following this blog [Welsh Genealogy] since my 50 years of genealogy have brought me to the Vale of the Dee.
