Local
people probably knew the mouth of the River Tawe as Sweyne's, which
became easily changed to Sweynes's (and countless other pronounciations
across a multilingual community speaking Latin, Old English, French,
Norse, and Celtic languages). For those of you who are still sceptical
there's a pub in town called 'Yates's', if you read this aloud you'll
see how the process happens, and if you're still not convinced listen
to how other people pronounce 'Yates's'.
The
Sweyn of the story is most likely Sweyn Forkbeard who was briefly King
of England 1013-14. At this time the scandinavians who populated parts
of the western coast of Britain were more interested in trade than military
conquest and it is likely that the trading post of 'Swenes's' would
have been well known along the coast of what would eventually become
the Bristol Channel.
In
the nineteenth century, Swansea citizens were extremely proud of this
Royal Viking foundation and valued it far higher than any Welsh connection
(not that there was one really). When Swansea's
Guildhall was built in the 1930s, considerable effort was made to
reflect the phenomenal history of the ancient borough in the art and
structure of the building. The photos here
