Eliana is very pretty. I think you need to stop telling family and friends the names you are considering! :)
Even if it was "foreign" (which I don't really think it is) that would be irrelevant because it is a middle name.
Are you thinking Grace Eliana or Grace Victoria Eliana or Grace Eliana Victoria? I really like Grace Eliana.
