A very common form of mistake is that of omitting the Christian name from the courtesy titles of the sons and daughters of dukes, marquises, and earls. The sons have the title “Lord” prefixed to the Christian and surname: for instance, “Lord Alfred Osborne,” “Lord Henry Somerset.” It is extremely incorrect to call either of these “Lord Osborne” or “Lord Somerset.” The daughters of dukes, marquises and earls have the title “Lady” before their Christian and surname; “Lady Emily Heneage,” for instance, must not be addressed as “Lady Heneage.” Should she marry a commoner only the surname is altered, the “Lady Emily” remains. This may all appear a little involved to those unaccustomed to titles, but neglect of these forms indicates very clearly a lack of savoir faire. It is a source of great annoyance to the owners of courtesy titles to have the Christian name omitted. Anybody, even a knight’s wife, may be a “Lady Smith” or “Jones”; the insertion of the Christian name before the “Smith” or “Jones” means that the possessor is the daughter of a duke, marquis, or earl.

Beginning a letter to the above.

In beginning a letter to any of the above a stranger would say “Dear Lady Mary Smith,” but the usual form would be “Dear Lady Mary.” Inferiors would begin by writing the lady’s title over the word “Madam,” or merely beginning “Madam” and writing the title at the end of the letter.

To an ambassador with conclusion.

In writing to an ambassador or his wife the title is placed above the word “Sir” or “Madam.” Inferiors would write “May it please your Excellency,” and would conclude with “I have the honour to be Your Excellency’s most humble, obedient servant.”

An archbishop.

In writing to an archbishop a correspondent would begin “Your Grace,” ending, “I remain Your Grace’s most obedient servant.”

A bishop.

To a bishop the form would be, “My Lord,” or “Right Reverend Sir,” or “May it please Your Lordship,” the last being, of course, the humblest form of address. The conclusion would be, I remain, “My Lord” (or “Right Reverend Sir”) “Your most obedient servant.”
