Everard Digby was the eldest son of Everard Digby, Esquire (who died in 1592) and his wife Maria (née Neale), daughter of Francis Neale of Keythorpe in Leicestershire. The conspirator was a cousin of Anne Vaux, who for years placed herself at considerable risk by sheltering Jesuit priests such as Henry Garnet. He was probably a near kinsman of the 16th-century scholar Everard Digby, but it is clear that the scholar, who died in 1605, was not his father, because as a Fellow of St John's College, Cambridge (a celibate calling) he could not have been married at the time when the young Everard and some of his 13 siblings were born, nor was he "Esquire", as the father is named in his "inquisition post mortem" of 1592.
