There are three good ways to search for celebrity facsimiles.

1. You can specify a complete name, first and then last:

    example: Gregory Peck

2. You can specify a complete name, last and then first:

    example: Peck, Gregory

3. You can specify a single name, first or last:

    example: William

This final example will return all facsimiles for celebrities whose first name or last name contains the text william.  Matches will include the last name Williams.

Finally, all searches are not case sensitive.
