As Royalist supporters ( despite the fact that Sarah's great uncle, James Temple, was convicted of regicide ), the Jennings ' loyalty to the crown, like the Churchill's, was repaid with court employment, and in 1673 Sarah followed her sister Frances into the household of the Duchess of York, Mary of Modena, second wife to James, Duke of York.

Although Frances was forced to give up the post because of her marriage to a Catholic, James did not forget the family, and in 1673 Sarah entered court as maid of honour to James ’ s second wife, Mary of Modena.

Her parents were James Louis Sobieski ( 1667 – 1737 ), the eldest son of King John III, and Countess Palatine Hedwig Elisabeth of Neuburg ( 1673 – 1722 ).

However, in autumn 1673, the Duke of York married the Catholic Mary of Modena by proxy, thus raising the possibility that James might have a son who would succeed to the throne ahead of Mary and Anne and thus give rise to a succession of Catholic monarchs.
