Given names and local versions often differ. Take for example the town of Amersham, Bucks. Lying both in a valley and on a hill it separates out officially into two parts - Old Amersham and Amersham-on-the-Hill, but locals called the latter Top Amersham and the older part simply Amersham at the time when we lived there. Well, I suppose in some ways, at that time Top Amersham (A-o-t-H) was superior, in that it had the modern houses and shops, plus the railway station with commuter access to London, but Old Amersham was more highly regarded locally, as it had the historical and more picturesque buildings, also the river Misbourne. Incomers preferred the superior sounding Amersham-on-the-Hill, but locals stuck to their guns with Top Amersham.
Then there are the Slaughters, Upper and Lower, with their unattractive name but lovely scenery. Upper and lower imply some sort of grade, rather than their actual geographical meaning. (Slaughter comes from an old term for "muddy", apparently.)
