Upon the death of her father in 1349 from the plague, Ramsey inherited his business,[1][2] including a London-based workshop that produced tombs.[5] Ramsey took on her father's debt and participated in property transactions.[1] She submitted accounts to the exchequer, showing that her father had not received more than half of the fees owed to him as the King's chief mason.[2]
She was a very successful mason-architect, and belonged to the elite of the profession in late 14th-century London. In the 1350s, she was contracted by Queen Isabella of France for the construction of the queen's tomb at the London Greyfriars, at a cost of over £100.[1] Ramsey is thought to be responsible for personally overseeing the construction and the placement of Edward II's heart in Isabella's tomb.[6]
Ramsey continued to oversee the business until 1399,[1] which is when she is thought to have died.[4]
