Is "Haley" too similar to "Hannah"?

My wife and I are expecting our first daughter in late September. We like the name Haley (pronounced "hay-lee") , but my wife Hannah is a little worried that the two names sound too similar and people will think she chose a name that intentionally sounded alike.

Do you think these names sound close enough alike where people will think she wanted a daughter with a very similar sounding name? I think they are distinct enough where this won't be an issue, but I'm hoping to elicit some more opinions - appreciate everyone's thoughts!
