Meautys was descended from a Frenchman who came to England to find employment at the court of Henry VII as an interpreter and spy. The family became established in Essex by the mid-sixteenth century, having acquired an ex-monastic estate at Stratford Langthorne, West Ham.
Meautys was recommended by his brother’s employer, Sir Francis Bacon*, to succeed the deceased Robert Shute, as MP for St. Albans in the 1621 Parliament, joining Thomas, sitting for Cambridge, as another of Bacon’s nominees in the Commons.
