Address Etiquette

How would I address a letter to a family in which the wife kept her maiden name? Would it be The Smith(husband's last name)-Jones (wife's last name) Family? Or The Jones-Smith Family? Or some other variation?Thx! Maggie

Dear Maggie,
It would depend on whether the wife kept her maiden name for professional use only and uses her husband's name socially which many women do. (I am well known in my field so I use my maiden name professionally, but socially I am Mrs. Jones not Miss Smith.)If this is the case with this couple, then address it to Mr.& Mrs. John Smith and Family. If not then address it John Smith, Mary Jones and Family.
