I don't know how that problem with the Welsh naming system can be used to find the origin of one's surname. Is there a formula or has someone devised a system for backchecking on names. I know the name Dicks and spinoffs are used fairly extensively in Wales , but was that always the name. I looked into this a while back but never reached any conclusion.
My closest match thru DNA was on the 37 marker test . I had one marker different with a Morgan. Most of my close? matches were to Pugh family members, but that was with 67 tested and diff's of 5 to 7. I checked all these out and found nothing of significance. Incidentally, the Morgan [close match] unfortunately had passed away. Harold
