A Visit to the Rookery of St. Giles and its Neighbourhood. (Volume 4): "The ground covered by the Rookery was enclosed by Great Russell Street, Charlotte Street, Broad Street, and High Street, all within the parish of St. Giles-in-the-Fields. Within this space were George Street (once Dyott Street), Carrier Street, Maynard Street, and Church Street, which ran from north to south, and were intersected by Church Lane, Ivy Lane, Buckeridge Street, Bainbridge Street, and New Street. These, with an almost endless intricacy of courts and yards crossing each other, rendered the place like a rabbit-warren."
