Then there is Cairo, Illinois. Pronounced KAY-roh. Like the corn syrup.
And Genoa, Nevada. Pronounced Geh-NO-ah.
Americans love to mess up words. It’s like an artform for us. 
Yeah, there’s countless examples of this. Here’s an article with 20 of 'em.
Or … pool?
Is any, or all, of that story for realz?
Anyway, how is Enroughty pronounced, when it isn’t being pronounced Darby? En-ruff-ty? En-roo-ty? En-rau-ty?
More to the first part, post 53 in this thread goes over the story. That one claims it’s not an English pronunciation, but a specific Southern US pronunciation of the name.
I am going to guess that it was bawdlerized into the latter potion of the name of that famous American tennis player.
Can’t find it, but I remember a limerick that started:
“A young man named Chelmondsley Colquon
Fed his baboon with a spoquon…”
Doesn’t help that even higher education gets in on the act of stuffing up pronunciations. See Magdalen and Caius colleges, pronounced respectively Maudlin and Keys.
Ooh, and I forgot one famous American pronunciation shift - Drumpf.
Not too many people would recognize who Alois Hiedler was.
And, I suspect, a great many people who do recognize that name are confused about just who he was. No, he wasn’t Adolf Hitler. And Adolf Hitler wasn’t born Schicklgruber either. The whole genealogy, per Heidler’s Wikipedia article, seems convoluted.
Alois Schicklgruber was born an illegitimate child of uncertain fatherhood. At a young age he became a step-child of Johann Georg Hiedler (who he later claimed was his biological father), and at the age of 39 formally adopted Hiedler as his surname – except that at this point, it inexplicably became Hitler instead of Hiedler.
He later had several children, some of whom died in early childhood. One of those children who unfortunately didn’t die in childhood was Adolf Hitler.
My often pasted quote from Wikipedia because its needed so often:
The street’s name is pronounced “HOW-stən”, unlike the city of Houston in Texas, which is pronounced “HYOO-stən”. This is because the street was named for William Houstoun, whereas the city was named for Sam Houston.
Also the street predates the founding of the city of Houston.
That, and there’s less of this elision stuff in the West Country (at least until you get to the western end of Devon, wharrr aaaahvereethang is ooonintellijable). Dorchester is “doorchester,” Sherborne is “shurbun” or “shareborne” depending on how long you’ve lived there, Taunton is “tawnton,” Bristol is “brisstul” and so on. Everything fairly close to the phonetic spelling.
ISTM that this has something to do with either the lack of Norse/Danish influence in the south of England, or the large number of Normans who lived there. The Anglo-Saxon spellings have been modified to conform to pronunciation more so than Oop North. For example, Sherborne was scirburnan to King Alfred, and its spelling gradually shifted over time.
Nguyen pronounced WIN
4th most common surname in the world. Most common surname outside of China.
Not really “win” except for people who aren’t used to the “ng” combination at the front of words.
Yeah, that’s just an Anglicized pronunciation (though I assume other languages without the ng initial phoneme also have similar accommodations.)
I know said limerick, approximately as follows (the name Colquhoun, by the way, is Scots, not “English English” – pronounced, roughly, “ka-HOON”):
A young man named Cholmondely Colquhoun
Once kept as a pet, a babquhoun.
His mother said, “Cholmondely,
I don’t think it colmondely
To feed a babquhoun with a spquhoun”.
Apart from Featherstonehaugh and Fanshaw the Guinness Book of Records lists at least two intermediate pronunciations: Freestonehugh ad Festonhay,
"* The Cat Who Walked Through Walls *
Almost a pity it didn’t remain as “Freestonehugh”, really, so that people could have fun amending the road signs.
Welcome to FREESTONEHUGH!"
Stone Hugh is Innocent!
