- Calvert was compelled to flee to Virginia after a group of rebels seized the fort and the governor's residence at St. Mary's. A provisional government was likely established, though no documentary evidence survives concerning its composition or official style.
- Hill was appointed by a commission issued by Governor Calvert in Virginia on 30 Jul/9 Aug 1646 to serve during his absence. However, Hill later asserted in a letter to Governor Greene that his authority derived from "His Lordship’s Council," arguing that Calvert's departure invalidated his power to appoint a successor, and that the Council acted out of necessity for public safety. Hill appears to have exercised authority until Calvert's return and forcible restoration to office by the end of 1646.
- Greene was said to have been named governor by Leonard Calvert on his deathbed on 9/20 Jun 1647. In the absence of a written will, the Council accepted the testimony of an eyewitness—who also served as Calvert's executrix—and proclaimed Greene as governor on 10/20 Jun 1647.
- Stone's commission was issued on 6/16 Aug 1648 in England. The date of his assumption of office is unknown, but he called the Assembly which sat satrting from 2/12 Apr 1649, and the first exatant document which he signed is dated 26 Apr 1649 (Old Style).
- The commission of Governor was declared "void and null" and the government was entrusted to the Council of Maryland by a proclamation of the Commissioners of the Council of State of the Commonwealth of England issued on 29 Mar/8 Apr 1652. The Commissioners restored Stone on 28 Jun/8 Jul 1652.
- The Commissioners, appointed by Lord Protector Oliver Cromwell for "Reduceing and Settling" of Maryland and Virginia, appointed a group of Maryland commissioners to govern the colony on 22 Jul/1 Aug 1654 who served until the surrender of administration to Fendall, holding a commission from the Proprietary.
- Philip Calvert's commission was issued on 24 Jun/4 Jul 1660 in England. The date of his assumption of office is unknown, but the first exatant document which he signed is dated 31 Oct 1660 (Old Style). There is a record of his swearing-in as governor and chancellor in the Court's proceedings on 11/21 Dec 1660, but it is not clear whether it was the first oath-taking.
- Charles Calvert's commission was issued on 14/24 Sep 1661 in England. He took the oath of office at the Court's meeting held on 26 Nov/6 Dec 1661, and inherited the title of baron and succeeded to the proprietorship of Maryland after the death of his father, Cecil Calvert, in England on 30 Nov/10 Dec 1675. The formal proclamation of Charles in Maryland took place on 4/14 Mar 1676. After attending a meeting of the Council on 19/29 Jun 1676, he departed for England sometime before 6/16 Jul 1676.
