Date: 20 Oct 2007
There are seven examples on ysearch of a distinctive type of R1b1b2 which can be identified with Welsh tribal patriarch Cadwgon ap Elystan Glodrudd. The DNA has differences showing that two branches are represented, believed to belong to two sons of Cadwgon ap Elystan Glodrudd. The traditional birthdate of Cadwgon is 1016 which seems reasonable as his son Gronwy was living in 1101
....
The Miles/Collins branch of this family shares a value of 24 for DYS 447 and 20 or 21 for DYS 576. It was the Miles data that enabled the identification with Cadwgon ap Elystan Glodrudd to be made. The Miles immigrant was a Welsh Quaker who went from Llanfanhangel Helygen, Radnorshire, Wales to Philadelphia, Pennsylvania in 1684. This area in Wales between the Wye and the Severn was the tribal territory of the family of Elystan Glodrudd. Not only that, but the only Miles family in Volume 2 of The Development of Welsh Heraldry by Michael Powell Siddons was seated at Harpton, Old Radnor. There are only about 8 miles between Harpton and Llanfahangel Helygen where the immigrant Samuel Miles attended Quaker Monthly meeting. The Harpton Miles family descended from Hoedlyw, son of Cadwgon ap Elystan Glodrudd. Three of the seven of this family are Prices (one spelled Priest). If one checks the online surname profiler, the greatest concentration of Price is in Radnorshire. Checking Siddons, the Radnorshire Prices descend from Idnerth and Llewelyn, sons of Cadwgon ap Elystan Glodrudd. There is also a doubtful Price line from Hoedlyw. Hopefully still more of this prolific Welsh tribe will join the databases so we can make the identification rock solid and clarify the branchings. I might note that I have an every-generation-descent from Cadwgon ap Elystan Glodrudd, but not in the male line. Probably every-generation-male-line-descents exist, or can be developed.
