An alley so called in the parish of St. Michael in Bassyngeshawe, in which Girdlers' Hall was situated, late Middelton Alley, 1520-1 (Ct. H.W. II. 628).
Girdlers' Hall (q.v.) may have been on or near the site, and has probably absorbed the alley, for Robert Belgrave, girdler, by his Will dated 1520-1, gave a parcel of land in this alley to the Girdlers of London, whose Hall was in this ward as early as 1438-9, and this gift may well have been for the extension and enlargement of the Hall.
The alley is described as in Bassyngeshawe Street, '5 H. VIII. 1523 (Lond. I. p.m. I. 42).
The name suggests an owner or builder.
