Margaret Brent emigrated to Maryland at the age of 37.  She never married, thus becoming a thriving businesswoman and landowner.   Upon the death of Governor Calvert, the Proprietor of Maryland, Margaret–not her brother Giles–was named executor of his affairs and charged with handling his debts, including those to soldiers under his command.

   She went to the General Assembly, knowing that they wished to repeal the tobacco tax, probably hoping that with her vote and voice she could convince the colony to pay the soldiers who protected them with the tobacco tax.  When she was denied a vote, she publicly protested all proceedings that took place.

 Came Mrs Margarett Brent and requested to have vote in the
howse for her selfe and voyce allso for that att the last Court
3d Jan: it was ordered that the said Mrs Brent was to be lookd
uppon and received as his Lps Attorney. The Gour denyed
that the sd Mrs Brent should have any uote in the howse. And
the sd Mrs Brent protested agst all proceedings in this pfit
Assembly, unlesse shee may be pnt. and have vote as aforesd

  Using her authority as the executor for Governor Calvert, Margaret then made a bold move: she began selling off cattle to pay the soldiers and prevent an uprising.  Lord Baltimore objected, but the General Assembly stuck up for her and wrote this letter as commendation:

We do Verily Believe and in Conscience report that it was better for the Collonys safety at that time in her hands than in any mans else in the whole Province… for the Soldiers would never have treated any other with that Civility and respect and though they were even ready at several times to run into mutiny yet she still pacified them… She rather deserved favour and thanks from your Honour for her so much Concurring to the publick safety then to be justly liable to… bitter invectives.

  Historians speculate that Lord Baltimore never forgave her over the cattle, and thus she moved to Virginia,  She acquired a large tract of land in Virginia, which she named “Peace” and lived there until her death in 1671.
