Etymology of the
Meaning of the baby name GWENETH.
The same as Welsh Gwynaeth
(q.v.), a feminine form of Gwynedd
("bliss, happiness"), the name of a medieval Kingdom, adopted as a masculine name. Also spelled Gwenyth,
Gwyneth, and Gyneth.
... Elised, son of Teudubr, King
of Brecheniauc, had also submitted to the King. Some of these had
been driven, as Asser tells us, by the exactions of Rodri the Great [King
of Gweneth = North Wales], and others by the tyranny of the "Aldorman"
Eadred (that is Ethelred), and of the Mercians to seek Ælfred's
protection. (British Place-names In
Their Historical Setting, McClure, 1910).
