 English Catholics provided the exiles with financial support into the 1770s.In 1689, around 2% of clergy in the Church of England refused to take the oath of allegiance to William and Mary; one list identifies a total of 584 clergy, schoolmasters and university dons as Non Jurors.This almost certainly understates their numbers, since many sympathisers remained within the Church of England, but Non Jurors were disproportionately represented in Jacobite risings and riots, and provided many "martyrs".
