Harvard University’s Houghton Library contains a manuscript entitled ‘Mrs. Furnivall transcript copies of old plays’ (MS Eng 1660), described as ‘Manuscript transcript copies of pre-Shakespearian plays made by Mrs. Furnivall, the wife of Frederick James Furnivall.’ This paper corrects the identity of 'Mrs Furnivall' suggested by the library's catalogue, and provides an overview of the life of Agnes Furnivall.
