Style of daughters of dukes/marquesses marrying courtesy peer of lower rank

[dpth...@gmail.com]

We may have discussed this before, especially in connection with Lady Mary Coke, but if so, I cannot find it by searching the group archive.

Horace Walpole writes to George Montagu in 1750: "I had a card from Lady Caroline Petersham..."

A footnote in the Yale Edition of the Correspondence says as follows:

"It was common usage in the 18th century for a daughter of a duke or marquess marrying a courtesy peer of lower rank than her own to add his title to her Christian name. Thus Lady Caroline Fitzroy on marrying Viscount Petersham became not Lady Petersham, but Lady Caroline Petersham; Lady Mary Campbell was known invariably as Lady Mary Coke; and Lady Caroline Cavendish is referred to as Lady Caroline Duncannon. The custom is occasionally followed today; see Ellen Countess of Desart and Constance Hoster, Style and Title, 1924, p. 23."

It appears the custom may still have been fairly common in 1924, but not much used several generations later when Patrick Montague-Smith covered the subject in his Debrett's Correct Form published in 1976 (see attached page).

Just found this about the daughter of the Duke of Roxburghe.
