Correct way to address a couple (greeting card)

In the UK, is this correct? the mans name first then the womans? on both card and envelope.

Its to my female cousin and her husband but his name should be first i believe?

 

Typically it doesn't matter.

- The Jones Family
- Dear, Mr. & Ms. Jones
- F. Jones & A. Jones

As long as the mail devilery system knows where the letter is going its all gravy.

Family correspondence doesn't need to be perfectly formal

 

Thanks zebulon, looks like il go for the middle one but with their names.
