Solved! It turned out to be a family friend who used her credit card with her Maiden name on it. She also has a weird Chiense legal name that no one knows about so that's why it didn't register. My mom texted me and told me that the subject came up while she was over the house. She vaguley remembered that I asked about someone with a last name "Ho".
I'm just happy to know that it's a gift meant for us and we won't have to return it.
For those who thinks snooping around your registry before your present gets there is a sin: Good for you! If I don't check my registry then I won't know when a gift has been mailed to my moms (she doesn't update me) therefore people won't be getting their thank you letters on time.
