Back in the day when I taught HS chemistry, I had a girl in class whose name was spelled "Tonya", and I pronounced it the way I normally would a name spelled that way, which is Tahn-ya, but she explained to me that it was pronounced Tone-ya, and that she had a sister whose name was Tanya. Poor girl.
Now I am a family physician, and I could probably go on for pages with the unusual names and spellings that I've seen over the years. Some are probably correct spellings, and I am not familiar with that particular name. Like, I have a 8 wk old patient named "Eian", which is pronounced like Ian. And an adult woman spelled "Mitchell", which she pronounces Michelle. I have heard of children who were probably named because the mom heard terms that were spoken in labor and delivery, like Placenta, Previa, and Female, pronounced like Tamale.
We used to have a list of patients who were named like famous people, like Betty Ford, Britney Spears, and others. We had a total of over 100 such names. We even have a Mary Disney, who is about the most un-Disney like person I've known. Wouldn't dare ask her if she were related to Walt Disney.
