Etiquette (and yes, it's still used) is the man's name goes first. Examples: * Mr. & Mrs. John Doe * Mr. John Doe & Jane Doe, M.D. * Mr. John Doe and Dr. Jane Doe * Dr. John Doe and Mrs. Jane Doe * Drs. John and Jane Doe * Dr. John Doe & Dr. Jane Doe * Mr. & Mrs. J. Doe * Honorable John Doe and Mrs. Jane Doe (only used for invitations to the couple.)
