Much has been written to shown that those who share the surname JONES are not always related by the Y-chromosome. For my own Y-chromosome, there are many "other" surnames that shared a direct match to my 12-marker test. [See post "Well, It's About Time", May 2, 2011.] The Welsh surnames that do share my Y-chromosome have been presented in a general sense on the post entitled, "Associated Surname", Jan.1, 2011. [Under Blog, http;//thejonessurname.blogspot.com.] The following post will give the connections for these surnames that share my Y-chromosome.
My JONES family begins in the Welsh genealogies with Tudor Trevor (JC-1). [See post, "Tudor Trevor", Dec. 27, 2010, under the blog: The Jones Surname.] His children are given in the post of January 26, 2011, under the title: "The Children of Tudor Trevor". The branches of these generation are given in a series of posts coded by the colors "Pink", "Orange", and "Blue" to help keep all the later generations identified as to their beginnings.
Only two sons of Tudor Trevor (JC-1) produce male descent; the second son, Llydocka (Llyddocka) (JD-2), and the baby of the family, Dingad (JD-3). Those who share this Y-chromosome by surname are listed below. The documentation for each surname is found in Dwnn, volume II, with the page numbers given.
