Wow, I really love how different accents and whatnot effect it differently, because it's different sounds. That's cool.
I'm from Australia so my accent is different to the pair of you, but even so I don't put as much of a "W" in my name when saying the "shua" bit.
I ended up with this:
Dʒaʃuə.
Does that seem right to you? If so I'm going to try writing that in Circular Added (23 Apr 2013, 6:21 PM)
---------------------------------------------
I can even see why it might be Dʒaʃjuə.
In fact, I think I like this one best
How interesting!
