Blanche Parry arrived at the
Royal Court with her aunt,
Blanche, Lady Troy, who was the Lady Mistress to
Edward VI and his half-sister Elizabeth I as children. She may have supervised the team of "
rockers". Thereafter, Blanche hardly left Elizabeth and almost certainly attended her during her imprisonment in the
Tower of London before she came to the throne. Her annuity or wage in the household for six months in 1552 was 100 shillings and she was allowed 30 shillings for horse fodder. Following Elizabeth's accession in 1558, as her epitaph at Bacton relates, Parry was sworn in as a
lady of the bed chamber. After
Kat Ashley's death in 1565, Parry was appointed the
Chief Gentlewoman of the Privy Chamber, and was one of those who controlled access to the Queen. She was friends with her cousin Sir
William Cecil, Lord Burghley, the Queen's chief adviser, and worked closely with him. Amongst the material rewards she received from Elizabeth were two
wardships and she acquired lands in
Herefordshire, Yorkshire and
Wales. Records show frequent gifts of clothing previously worn by the queen. She gave Elizabeth presents of silver, including a double porringer and four silver boxes with silver gilt covers. For New Year's day 1572 she gave the queen a flower of gold enamelled with rubies and diamonds, which the queen later gave to Elizabeth Howard, in 1573 Parry gave the queen a jewel of mother-of-pearl set with gold hanging from three gold chains with an agate pendant, and in 1575 a gold flower enamelled green with three white roses with sparks of ruby, and in the midst, a fly. In August 1582, Blanche Parry wrote a letter on behalf of Miles Pendred of
Northbourne who was in need of legal help. His wife Anne or Elizabeth Lewin had been one of the queen's nurses, and her brother Thomas Lewin had also been a servant in Elizabeth's household. Parry commissioned the first known map of
Llangorse Lake in 1584 to aid the deliberations in a court case in which she became involved. In January 1587, she gave Queen Elizabeth a jewel with a "
serpent's tongue" set in gold, thought to serve as a talisman against poisoning. After 1587, responsibility for the queen's personal jewellery passed to
Mary Radcliffe. Parry made an
inventory of the jewels, now held by the
British Library, listing 628 pieces delivered into the custody of Mary Radcliffe. William Cecil supervised both her wills; his handwritten notes survive for her first will dated 1578 and he was supervisor for her final will dated 1589. ==Death and burial==
