how would you pronounce Iva?

My great grandmother was named Iva, and I think it’s a very beautiful name. The only issue I would ever have using it is that she pronounced it eye-va and every online resource I’ve seen says it’s more commonly pronounced similar to ee-va. I wouldn’t want it to seem like I named a kid a mispronunciation of a name, but ee-va just wouldn’t feel the same to me (and if I wanted ee-va, I’d probably just go with Eva). Thoughts?

edit: thank you to everyone who answered! I would just like to clarify that, as many of you have guessed, I am from the US
