My sister is Sahra.
Mum & dad went through 3 spellings to get people saying it right.
Sara (se rah)
Zara (Ze rah!)
Then Sahra (Sah rah)
She still gets Se rah alot, but its a bit more common these days, so people are getting used to it.

I went to school with a Naomi, who always got Nyomi. There was a local girl actually called Nyomi.
