Addressing STD envelopes

SLAHSarah

I need advice on addressing the envelopes for my save the date cards.

Here is the situation:
Fiance's cousin (over 18)  is in college and has a significant other who will be invited.  He would prefer for us to send the invite to his parents house.  Do I mail out 2 separate invites?

 I don't feel that I should write:

Mr & Mrs. Fiance's Uncle Last Name
Cousin and guest name
1234 Main Street
Sunnytown, FL  12345

Or can I just write:

The ______  Family
1234 Main Street
Sunnytown, FL  12345

Two separate invites.

Two invites.  And, since the cousin and his GF aren't married, it should be

Mr. First Last
Guest
123 Sesame Street
Anycity, State
ZIP

Hi, I'm having the same problem and was looking through the posts to make sure I didn't ask a question that was already asked.

What about addressing a family (a mother and daughter live together)
could you type The Smith family in that case ? Or should both names be typed out ? Mother & Daughter Smith ?
