Why do people keep mispronouncing my name?

My name is Divine--like the English word, "divine". There are no tildes,
no accent marks, no umlauts, or funky letters like æ...nothing shady going
on here. Yet every time someone reads my name, i always hear:
"Now, excuse me if i mispronounce this...is it {'Divon', 'Devin',
'Div-in', 'Div-EE-nae' (yes, this one actually happened), etc.}...?"
I know my name isn't the most common name in the world, but it's an
English word! I can understand if you have a "regular-looking" name that
has an abnormal pronunciation. I imagine the protocol there would be that
you sound it out as best as you can first, then go for the funny
pronunciations. But why do people reverse that order with my name?
To make matters worse, after learning how my name is pronounced, and its
place in the dictionary, a large percentage of those people go on to
misspell my name as Devine!
Is there something about dialects, or the history of this word, or
something, that makes people's brains stop working when they read my name?
Thanks for reading.
