Hull has a good position, it's the only city in East Yorks, all the rest being countryside, small villages. It's close to the coast and rivers, and it's not too big.
The name Beverley comes from Beaver, which used to be common in the area, being rich in watercourses and Meres, mentioned by Chaucer in the Summoners tale
"Lordings, there is in Yorkshire, as I guess,
A marshy country called Holderness"
As a side note "Little John" of Robin Hood fame may be a Beverley man called Reynolde Greenleaf, according to reports he had a long standing feud with the Sheriff of Holderness, enjoyed beating up his men, and was by all accounts "a bit of a lad". It is postulated that "Little John" is in actuality the person Reynolde Greenleaf from near
Beverley in the
East Riding of Yorkshire (fact or fiction, Robin Hood, Channel 4)

The siege of Hull was the first major action of the English civil war, where the people told the King to "sod off" and barred his entry to the town, we of course kicked his arse and won.
