Life
He was the son of Morys Wynn ap John, whom he succeeded in 1580, inheriting Gwydir Castle in Carnarvonshire. John was educated at All Souls College, Oxford (1570, awarded BA 1578) and studied law at Furnival's Inn (1572) and the Inner Temple (1576). He claimed to be directly descended from the princes of Gwynedd through Rhodri ab Owain son of Owain Gwynedd. The known male line from his family died out in 1846 with the death of Dr. Rice Wynne of Shrewsbury descended from Sir John's younger full brother Robert Wynn of Maesmochnant, and it is presumed the senior male line passed to the Anwyl of Tywyn family although it is unconfirmed due to accounts of possible lost relatives such as previously not much talked about son(s) of Sir Richard his grandson of whom one may have survived to have offspring yet records past the baptism and death records for them in the Llanrwst parish registry is scant, as two known branches from Gwydir survived past the main line fathered by Sir John, the descendants of his full brother aforementioned and the descendants of his half-brother Edward Wynn of Ystrad which became the Wynnes of Llwyn and Pengwern who died in 1835 with the death of Maurice Wynn of Pengwern.
His mother was Jane (Siân) Bulkeley, daughter of Sir Richard Bulkeley and his wife Catherine Griffith, and sister of Sir Richard Bulkeley, head of the Anglesey branch of a powerful landowning family, who originally came from Cheshire.
