Oliwia

[WrappedInABlankie]

Apparently this is the 'posh name for Olivia.. Am I the. Only one who has never heard of this and would pronounce it oli-wa

Polish, not posh.

I think perhaps you've misread "Polish" as "Posh" somewhere? see number 7

Nope she thinks it posh, I said polish and she said everyone 'back in the day' was called Oliwia in the posh parts.. Don't know how far back in the day as she's 19

I've never seen this before and as an English speaker it just looks like Olivia spelt incorrectly.
It's the polish versions and in fact pronounced in the same way.

It sounds like Jonathan Ross trying to say Olivia.

It's Polish. Name of someone I was at school with (Polish parents, emigrated to the UK in the early 60s).

It's the Polish form of Olivia and is pronounced the same. It's not a posh version of Olivia

Unless you are Polish, it looks like misspelt name.

Definitely Polish.

Echoing everyone else but yes, definitely Polish (or at least Eastern European). Just like Weronika and Wiktoria. Names that we recognise so they just look slightly wrong but aren't.

Please assure your friend that w's have never been pronounced as v's in the a English language.

The only thing I can think of, and it's really clutching at straws here, is that Dickens had a character (Sam Weller) who transposed V's and W's. So he would find something 'wery' hard, or would go 'avay'. I think the common interpretation is that this was CD's rendition of cockney. So definitely not posh!
