I received this wonderful line, down to Charlemagne, a number of years ago from Colonel Paul L. Nichols, USA retired. He and his wife, Marjorie Foster Nichols, had spent many tedious hours of research in Somersetshire and in Devonshire, tracing this line and verifying their entries. This record of their work has been accepted by the "Order of the Crown of Charlemagne in the United States" and with their aid I was also able to obtain a lifetime membership in this organization.
I don't know if Col. and Mrs. Nichols are still living (I hope they are) since I have lost contact with them. Their last known address, in case some of you would like to correspond with them was:
Lt. Col. Paul L. Nichols 1475 Yountville Cross Road Yountville, CA 94599
