In 1887, John Bartholomew's Gazetteer of the British Isles described St Marylebone like this:
Marylebone, parl. bor. and par. (St Marylebone), Middlesex, in NW. of London, 1506 ac., pop. 154,910. Marylebone returns 2 members (2 divisions, viz., East and West, 1 member for each division); the old parl. bor. of Marylebone included also the pars. of Paddington and St Pancras, and returned 2 members.
The location is on Marylebone High Street.
A Vision of Britain through Time includes a large library of local statistics for administrative units. For the best overall sense of how the area containing St Marylebone has changed, please see our redistricted information for the modern district of Westminster. More detailed statistical data are available under Units and statistics, which includes both administrative units covering St Marylebone and units named after it.
