Hundreds or Wapentakes: Lancashire used the term Hundred to define an ancient area of administration which probably derives from the area having to supply 100 armed knights to serve the monarch or similar. For Taxation purposes, the Hundred was used for division until into the 19c.
County Hundreds are:
Amounderness: roughly North of Preston to South of Lancaster
Blackburn: east of Preston to Yorkshire West Riding
Leyland: south of Preston to Standish
Lonsdale North: Barrow-in-Furness, Carlisle
Lonsdale South: Lancaster, North Lancashire
Salford: roughly Greater Manchester
West Derby: all of west Lancashire to the Mersey

West Derby is now a part of Liverpool and encompasses those areas outside the original centre of Liverpool. It includes such places as Toxteth Park ,Everton, Wavertree and indeed West Derby itself.
Old Swan is an area in Liverpool 13. There is a pub there called the Old Swan, probably named for a lake with swans on somewhere in the area. The full length of the Swan runs from Queens Drive/Prescott Road and extends further to Prescott Road/Green Lane, the main shopping area begins at Derby Lane/Presott Road.

It stands on the Mersey, and by its position, and wealth, has become the second port in the kingdom. It is, on the whole, a very handsome and commodious town; and the public buildings are numerous, and highly ornamental to it. The churches, the municipal edifices, the custom-house, the exchange, the charitable institutions, the markets, and the theatres, seem to have been constructed for the gratification of taste, as well as for their various and peculiar uses. But the docks are the most remarkable features of the town; and the construction of them has enabled it to take its distinguished position in the commerce of the world. Its inland trade is aided by the rivers Irwell and Weaver, by the canals, and by the railroads, which converge there. It is 206 miles from London. Population, 286,487.
