A part of the reason 'Kingston' never took hold, was because people thought it was a bit pompous for someone to think they could buy us even if (or especially because) they were the King, so just declined to use that bit.Hull has a few etymological theories.
1. It’s from Old Norse hyl- < Proto-Germanic *hulh- which means a ‘pool in a stream/river’. This would be cognate to modern Danish and Norwegian høl.
2. It’s from Old English hula (plural of hulu) < Proto-Germanic *hul- which means ‘covering’.
3. It’s from Proto-Brythonic *hʉl < Proto-Celtic *soulos (with regular sound change of /s/ > /h/ in Brythonic), probably from a verbal root ‘to press’.
The original name was therefore either *Hylvík (settlement by a pool in the river) in Old Norse, *Hulawíh in Old Northumbrian English (settlement of coverings/huts) or some old Celtic river name with the Germanic settlement suffix -vík/wíh/wíc. The Old Norse or Old Northumbrian forms vík/wíh are the origin of -wick and Wyke, identical to -wich in southern English dialects.
Also, at the time, it was a whole collection of settlements, each feeling they were the main centre, such as Marfleet and Sculcoates, which was the biggest and had little connection to what became the business centre.
We're all just tribal, it's only the scale that varies.
