HI, no, no family information, just a THANKS for this entry! I have a female ancestor Morgan (married name, David suspected maiden name) whose given name is records is Givyn, Gwen, Guin. A group of us have settled on the name of Gwen, rather than a noted Gwenllian in Welsh records.
Biggest thing here, though, is the WELSH origin. I had assumed that my John Nicholls forbear was from England (his daughter, Michal, married an Englishman in the Virginia Colony about 1680). Now I wonder!
