Re: How do you pronounce Johanna?
This might have been my grandmother's name. (I've made mention of this before, so sorry to repeat myself!)
She was always called Hannah,but occasionally said she was quite sure she was really called Johanna.Not that she didn't know her own name,but she had been orphaned young, and I think papers had got lost.
Going by that, I'd guess she, and I would pronounce it Jo+Hannah.
I live in Canada,east coast.
