The wife of the eldest son of a marquis should be addressed as "Lady A." by the upper classes, and as "My Lady" or "Your Ladyship" by all other classes.

The younger sons of a marquis should be addressed as "Lord Henry B." and "Lord Frederick B." by the upper classes, and as "My Lord" or "Your Lordship" by all other classes.

The younger sons of earls, and both eldest and younger sons of viscounts and barons, only bear the courtesy title of honourable. The daughters of viscounts and barons also bear the courtesy title of honourable. This title should never be used colloquially, "The Hon. Cecil Blank," "The Hon. Mrs. Cecil Blank," and "The Hon. Mary Blank," should be styled "Mr., Mrs., and Miss Mary Blank."

Baronets should be addressed by their full title and surname, as Sir John Blank, by the upper classes, and by their titles and christian names only by all other classes.

Baronets' wives should be addressed as "Lady B." or "Lady C.," according to the surnames of their husbands: thus, "Sir John Blank's" wife should be addressed as "Lady Blank" by the upper classes, not as "Lady John Blank"—to do so would be to give her the rank of the wife of the younger son of a duke or marquis instead of that of a baronet's wife only—and as "My Lady" or "Your Ladyship" by all other classes.
