A Dictionary of the Booksellers and Printers who Were at Work in England, Scotland and Ireland from 1641 to 1667/Simmons (Mary)
SIMMONS (MARY), printer in London; Aldersgate St., 1656-67. Her name occurs in the Hearth Tax Roll for the six months ending Lady-Day 1666. She is returned as having thirteen hearths, a greater number than any other printer on the roll, so that her premises were large. She is probably identical with the Mistress Simmons mentioned as the "Custom House printer" in the return of printing houses made in 1668, and was perhaps the widow of Mathew Simmons. [P.R.O.
