In 1640, on his uncle's recommendation, Witherley was appointedMaster ofSir John Gresham's Grammar School atHolt in his native county.[1] In October 1642, it was reported to theFishmongers' Company, the school's trustees, that there had been a long outbreak ofsmallpox in Holt and that the school had had "noe schollers since Midsomer last yett the schoolmaster hath attended..." However, in May 1643 the Fishmongers heard that Witherley had been "betaking himselfe to the studie and profession of phisick" when he asked for a six-month leave of absence to enable him to take a medical degree in theNetherlands. This request appears to have been refused, as Witherley did not depart until after he had resigned his position as Master of the school in September 1644.[1]
In 1688, at the time of the birth ofJames Francis Edward Stuart, son and heir ofKing James II, when the new prince was widely believed to have been smuggled into the Queen's bedchamber in a bed-pan, Witherley was Second Physician to the King and gave evidence that he had been present at the birth. He deposed that he "saw Mrs Labadie bring the child from the midwife, and carry him into the next room... and saw the child before he was cleaned..."[4] A strongroyalist, he was later accused by theWhig historian Burnett of being complicit in a plot by King James to turn a changeling intoPrince of Wales so that there could be aRoman Catholic heir to the throne.[1]
