- Haydon Street
- East out of the Minories, at No. 40, to Haydon Square. Partly in Portsoken Ward, but the greater part of the street lies outside the Ward as at present constituted in the Minories' precinct, now reunited to the parish of St. Botolph, Aldgate (P.O. Directory).Earlier forms : "Heydons Yard" (O. and M. 1677). "Heydon Yard" (Rocque, 1746, and Strype, ed. 1720). "Haydon Yard" (Horwood, 1799-Lockie, 1910).The earliest mention of "Haydon Street" seems to be in Greenwood's map, 1827.The name is derived from the family of Heydon, who were well known in the district. Captain John Heydon occupied the Minories officially as Master of the Ordnance, etc. 1627-1642 (Tomlinson's Hist. p. 136), and took a great interest in the precinct.Wheatley says Alderman Heydon was ground landlord. But Alderman J. Haydon was alderman of Aldgate Ward, 1582.
