How do I change the title in AirDrop?

[Snapple3]

Hi, need some help.

I have 10.10 on both my 2012 rMBP and 2011 iMac and I noticed when I connect with AirDrop, it shows 'Mom' under the user name and picture. This shows up on both the iMac and rMBP but different usernames.

Where is this name pulling from and how can I delete it?

I have attached a picture for reference.

Thanks in advance.

I believe the name and picture comes from the user's contact card.

I guess it is at

System Preference/Sharing/Computer Name

Otherwise it'll be the name, in Contacts, of the Apple ID for the computer.
