I would address it to:
Sir and Mrs. John Doe
Street address
City, State and zip code
A baronet is addressed as "Sir", and his wife as "Lady". Exactly how to address the envelope is a little dicey , but "Sir John Doe and Lady Doe" would be acceptable, I would think.
Mr. & Mrs. <lastname>
Dr. & Mrs. John Smith
Dr. Mary Smith and Mr. James Doe
How about Mr. and Mrs.
if addressing an envelope it would be to the Reverend Canon or just Canon. His wife would be Mrs... The oral address would be Canon, and his wife Mrs.....
Type your answer here... Mr. and Mrs. Mark Henderson
Drs. _______ and ________ Smith
Pastors George and Martha Maloney
Address the man in the same manner as if his wife were not a dentist.
That would be: "Dr. John and Mrs. Jane Whomsoever".
When addressing a business envelope where the husband is Mr. and the wife is Dr., the proper way to format the names is to list the titles in alphabetical order. Therefore, you would address the envelope as "Dr. and Mr. [Last Name]." For example: "Dr. and Mr. Smith." This shows respect for both titles.
