There have been two baronetcies created in the 17th and 18th centuries for persons with the same surname, Wynn; these titles were given to families from North Wales, United Kingdom:
The surname Wynn is derived from Welsh: gwyn (which can mean "white" or "blessed"),[2][3] (soft mutation form wyn). The family name Wynn originates from North Wales. The first mention of the Wynn family of Gwydir was recorded by the children of Maredudd ap Ifan (died 1525), and the name was subsequently adopted as a surname by Maredudd's grandchildren, including Maurice Wynn (died 1580), ancestor of the Wynns of Gwydir; whereas the Wynns of Bodvean (subsequently Baron Newborough) descended from John Wyn ap Hugh (John Wynne, died 1576).
