SIR JOHN BALDWIN of Buckinghamshire, died Oct 24, 1545. Inquest of his estate was held at Aylesbury, Dec 22, 1545. "He was a member of the inner temple and appointed reader in 1516, 1524 and 1531. He twice filled the office of treasurert, 1524 and 1530. He was of Bucks in 1510 (on commision of the peace)..... In 1520 he was a man of sufficient mark to be nominated on the sheriff roll, but he was not sellected by the king. In In 1529 he was on the commision to hear causes in chancery committed to then Cardinal Wolsey, then lord chanceller. In 1530, on Cardinal's fall,he was selected to hold inquisition as to the extent of his property in Bucks. He set in the House of Commons once, being burgess for Bendon in Wiltshire in 1529. In 1530 he was appointed attorney general for Wales and the Marches, and also of the county Palntine of Chester and Flint. His patent as sarjeant-in-law is dated Nov 16, 1531. According to Dugdale he and Thomas Willoughby were the first serjeants-in-law to receive the honor of knighthood. this was in 1534. In 1535, he was appointed chief justice of common pleas and almost the first cases in which he acted in a judiciary capacity were the trials of Bishop Fisher and Sir Thomas More for treason. He also acted in the same capacity at the trials of Anne Boleyn the same year. He seemed to have lived principally at Aylesbury. He aquired a house and site of the Grey Friars and the manors of Ellesberough and Durich" (Dist Am. Biog.) Colonel Chester says he was given the Manor of Dunridge in Bucks by Henery VIII shortly after 1541, and that he died in1545. When he died he left no surviving sons. The D.N.B. article says he had a son William, who married Mary Tyringham, but died during his father's lifetime. The estate passed to his heirs, Thomas Packington, son and heir of his daughter Agnes, wife of Robert Packington, and to John Burlacy, son and hair of his daughter Petronilla. The manor then passed to Thomas Packington's son and heir, John, who in March 1577/78 alienated to Henry and Richard Baldwin, who in 1579 paid the taxes on the manor. These are considered by Col. Chester to be father and son. In 1553 two brothers, Richard and John occupied Dundridge. This was but eight years after the death of Sir John. These brothers are probably the sons of Richard - the brother of Sir John.

iii. Robert Baldwin was born about 1475. He died before 16 Apr 1537 in Dundridge, co. Bucks, England.
