Stationery question

Rubygirl

I need to order stationery to be used to send out thank yous, etc. from all of us.  I have personal stationery with just my name on it, but need something for when I have to sign H's name too.  So, would you have it personalized to read (last name is made up):

The Kelly Family

 or

The Kellys

 Is one more formal than the other?

I would do "The Kelly Family"

I think "The Kelly Family" sounds better.
