St. Amand’s modest family background compelled him to earn his own living. After completing his education he found employment as a secretary to lord keeper Williams, bishop of Lincoln, who probably recommended him to the corporation of Stamford in 1624 after one of the borough’s Members, Sir George Goring, chose to represent Lewes instead. St. Amand may also have owed his seat to Goring, with whom he was later connected.
Williams was dismissed from the keepership in September 1625, whereupon St. Amand probably lost his job. In September 1628 Goring awarded him an annuity of £40 charged on his estate.
St. Amand remained on good terms with Goring and was one of the trustees for Lady Goring in a property settlement made in 1641.
St. Amand lived at East Greenwich from at least 1647, and was buried there on 1 Aug. 1664, by which time he was in his seventieth year. His will reveals that his estate consisted only of an office in Ludlow, the arrears of an annuity on lands in Yorkshire and his claims on the customs farmers of Charles I. Such sums as could be raised he directed to be divided between his wife and seven surviving children. His son, James, represented St. Ives in 1685.
