The present (Compton) Marquess holds the subsidiary titles of Earl of Northampton (1618), Earl Compton (1812), and Baron Wilmington (1812), the first in the Peerage of England, the latter two in the Peerage of the UK.
Northampton is a large market town and a local government district in central England on the River Nene, and the county town of Northamptonshire, in the English East Midlands region.
Northampton is the most populous district in England not to be a unitary authority, a status it failed to obtain in the 1990s local government reform.
Northampton's growth was accelerated in the 19th century, first by the Grand Union Canal, which reached the town in 1815 and later the coming of the railways.
