You can build a hash, but perhaps you need to store arrays as the hash values, not the strings directly.

Or you can build an array and a hash, and preserve multiple names only in the array.

Or of course you can just iterate over the array to find the names, but that's very inefficient, especially if you do it repeatedly.
