I can't find this name spelled like this anywhere

So my best friend is having a girl. At first I thought it was pronounced "Eli" and I thought that was a boy name, but maybe I was wrong. So I said I loved it because I thought it was a unique way of spelling it. Then she tells me it's pronounced "Ellie". I can't find this spelling anywhere, and I've never heard of it being spelled this way. Honestly I thought it was a legit way of spelling the name. Is this a tragedeigh? I'm wondering if I should mention this spelling doesn't make sense with how it's supposed to be pronounced. I just don't want everyone looking at the spelling and think she named her daughter "Eli".
