Lord Baltimore had always managed his proprietorship from England, where he worked to keep political support for the colony, as well as to prove his loyalty (as a Catholic) to the new government of Protestants. He had appointed his brother as governor and to manage his lands. During the emergency after Calvert's death, the Provincial Court on January 3, 1648 appointed Brent attorney-in-fact for Lord Baltimore, as there was no time to contact him about financial matters, and he had not appointed a successor to Calvert. She collected his rents and paid his debts.
