Does the husband's name come first in the greeting of an informal letter to a husband and wife?

== == * The envelope should be addressed to Mr. & Mrs. John Smith. Informally, one would write, "Jane and John Smith" in the salutation, as traditional, published etiquette states that, outside of the traditional "Mr. & Mrs." or "Dr. and Mrs." the wife's name is always first. Please see Miss Manners' Guide to Excruciatingly Correct Behavior (p 603) and Crane's Blue Bookof Social Stationery (pp. 89, 108, 110, 111, 112, 113, 603).
