Short answers, pulled from the story.
Bellott v Mountjoy was a lawsuit heard at the Court of Requests in Westminster on the 11th of May 1612. Stephen Bellott, a Huguenot, sued his father-in-law Christopher Mountjoy for an unpaid dowry of £50 and a promised bequest of £200 that had been agreed at the time of Bellott's marriage to Mary Mountjoy in 1604.
Bellott v Mountjoy is significant because William Shakespeare was a material witness in the case and his signed deposition survives among the court papers. The documents reveal that in 1604 Shakespeare was lodging at the corner of Silver and Monkwell Streets in Cripplegate, London, which is the only documented evidence of a specific London address where Shakespeare lived.
Shakespeare confirmed in his deposition that he had acted as a go-between in the courtship of Stephen Bellott and Mary Mountjoy, a role that other witnesses also described. He stated, however, that he could not remember the specific financial terms of the marriage settlement, which prevented the Court of Requests from ruling directly on the dowry dispute.
The records were discovered in 1909 by the Shakespeare scholar Charles William Wallace at the Public Record Office in Chancery Lane, now part of the National Archives. Wallace published his findings in the October 1910 issue of Nebraska University Studies.
Christopher Mountjoy was a tyrer, a manufacturer of ladies' ornamental headpieces and wigs, and the father-in-law of Stephen Bellott. He was the defendant in the 1612 lawsuit and had lodged Shakespeare in his house at the corner of Silver and Monkwell Streets in Cripplegate. Even after the London Huguenot church overseers awarded Bellott 20 nobles, Mountjoy still had not paid a year later.
At the beginning of 1604, Marie Mountjoy worked at court supplying a helmet and trimmings for Queen Anne of Denmark's appearance as Pallas Athena in Samuel Daniel's masque The Vision of the Twelve Goddesses. A surviving bill records her charge of £59 for this work, vouched by the Lady Walsingham.
