Choose contact name manually?

In my contact list, I entered a number of "household" contacts combined together. For example, "Bob Sally Smith", with the corresponding e-mail addresses, phone numbers, etc. The problem is that, if the e-mail address is also associated with a Facebook contact, it overrides my preferred naming system and shows the name of the Facebook contact. For example, if the e-mail address were Bob's in my example, it would show "Bob Smith" instead of the combined name.

Is there a way to force it to use the name I prefer it to use?

Note that this may be specific to my phone - Motorola Droid. A friend of mine has the Droid X and I might see if his does the same thing...
