In 1887, John Bartholomew's Gazetteer of the British Isles described South of the Witham like this:
Witham, South of the, par., Lincolnshire, pop. 2.
The location is approximately that shown for "South of the Witham" in the Boston area enlargement on the 1888 Sanitary Districts Diagram for Lincolnshire, given its location relative to the boundary of Boston parish as overlaid by us on the New Popular OS map. The name has not been located on a topographic map, but the area appears to be between the straightened modern river and the loops of the old course.
South of the Witham is now part of East Lindsey district. Click here for graphs and data of how East Lindsey has changed over two centuries. For statistics about South of the Witham itself, go to Units and Statistics.
