grammar - My family *is* or My family *are*?

I've done a bit of research and I understand that "family" should be preceded by singular or plural verb depending on how you want it to be treated. For example,

His family is one of the oldest in the county.

and

His family are all doctors.

These are apparently both correct.

But in the following instance, could a grammar expert tell me which should be be?

When his family are abducted

or

When his family is abducted

?

Thanks.
