Maidenhead Alley
   1) East out of the Minories, not far from its junction with Aldgate High Street, and communicating with Chequer Yard (Strype, 1720 and 1755).
   Former name : "Red Cross Alley" (O. and M. 1677), but not so long as Maidenhead Alley.
   Named after the sign.
   The Maidenhead was the crest of the Mercers' Company and may have been used sometimes as a sign on this account. It was also the crest of the Duke of Buckingham and of Katherine Parr.
   Site rebuilt before the 19th century.
   2) East out of Aldermanbury, near Cateaton Street (Hatton, 1708).
   Not named in the maps.
