business letters

[noah13jeff]

Here is how I address my business letters to married people with the same last name:
Mr. and Mrs. John Smith
123 Main Street
Anytown, USA 12345

Dearn John and Mary,

My question is how do I handle the top line for a married couple with different last names??

Thanks,
Jeff Dickison

If they have different names, I would use 'Mr X & Mrs Y'
