6. Saxon and Danish Names.

On the other hand, the names of many of the great political divisions,
especially in the south and east of England, mark the Saxon
settlements, such as Essex (the East Saxons), Sussex (the South
Saxons), Middlesex (the Middle or Central Saxons). In the same way
the settlement of the two divisions of the Angles on the coast is
indicated by the names Norfolk (the North folk) and Suffolk (the South
folk). (See map facing p. 24.)

The conquests and settlements of the Danes are readily traced by the
Danish termination "by" (an abode or town), as in Derby, Rugby,
Grimsby. They occur with scarcely an exception north of London. They
date back to the time when King Alfred made the Treaty of Wedmore
(S56), A.D. 878, by which the Danes agreed to confine themselves to
the northern half of the country. (See map facing p. 32.)

7. Norman Names.

The conquest of England by the Normans created but few new names.
These, as in the case of Richmond and Beaumont, generally show where
the invading race built a castle or an abbey, or where, as in
Montgomeryshire, they conquered and held a district in Wales.

While each new invasion left its mark on the country, it will be seen
that the greater part of the names of counties and towns are of Roman,
Saxon, or Danish origin. With some few and comparatively unimportant
exceptions, the map of England remains to-day in this respect what
those races made it more than a thousand years ago.
