Robert Malyn was a surgeon of some importance in Manchester in the early eighteenth century. He was born before 1665 and appears to have spent his early years in Nottingham. On 30 March 1686, at St Mary's, Nottingham, he married Katherine, daughter of Richard Massey (or Mascie) of Sale, Cheshire (see Nottinghamshire Parish Registers: Marriages, vol. 7, 1905). Malyn practised in Manchester, Sale and Nottingham. His daughter Anne married Dr Peter Mainwaring (see above) in 1731.
Robert's son, Massey (or Massie) Malyn (b 1688, d after 1729), was admitted to Queens' College Cambridge in 1705 and obtained an M.B. in 1710. He matriculated from Brasenose College Oxford in 1718, aged 30, and was awarded a LL.D. from Cambridge in 1723 (Alumni Cantabrigienses). He was presented to the rectory of Ashton upon Mersey, Cheshire, in 1717, and he also practised medicine in Sale (see Eighteenth Century Medics).
