Hi Carol, There is no easy answer to your question.I am a descendant of the Dyess family that we have traced back to the Virginia/North Carolina region. We are actually on FB under Dyess genealogy where we discuss topics such as your question. A lot of us have heard thru the years that we come from Wales, Scotland or Holland but we have no proof. Sounds like you could educate us and learn some things along the way. We also have a Dyess family website on myfamily.com.If you're interested,let me know and I'll send you an invite. My email is email@example.com.
