Bath is of course in Somerset and the Somersets were a family of nobles from the House Of Beaufort - looking on Google maps there are roads called Beaufort Place and Beaufort East just to the south of 'Worcester Park' and 'Worcester in Bath.
Edward Somerset was appointed Keeper of the Great Park which was created for Henry VIII around Nonsuch Palace - land on which the settlement of Worcester Park (named after him) was later built.
Well, that's my theory. Any more ideas?
