Let’s say that Genevieve Stapleton falls in love with and marries Cuthbert Stapleton, to whom she is not directly related. Genevieve, having feminist tendencies not unlike those of Hillary Rodham Clinton, wants to keep her maiden name in her last name. Would she therefore be known as Genevieve Stapleton-Stapleton?
Yes if she was a pretentious twat. People will do anything, so I don’t know why this won’t happen eventually.
If she’s such a feminist, then why would she want to change her name at all? She would just keep her maiden name.
My high school gym teacher wanted her son to have her name, so Ms Mason’s kid got her last name as his first name, Mason. And the dad’s last name, Burns. Or together, Mason Burns. Then she and the dad divorced, so she decided to add her last name to his last name, hyphenated. So he was known henceforth as Mason Mason-Burns
It’s probably happened many times, since women have been hypenating their names for decades. It’d look very silly but I don’t see how it makes the woman a pretentious twat.
Eleanor Roosevelt didn’t do it when she married Franklin Roosevelt. If it was good enough for Eleanor, it should be good enough for the fictional Genevieve Stapleton.
This is a common occurrence in Puerto Rico where they hyphenate their paternal with maternal name. Also agree with Harmonious Discord’s answer.
I don’t know that it would be seen as pretentious in a Spanish-speaking culture where everyone has two last names. The choice would be between one form of awkwardness and another, since having only one last name would make people wonder why.
Isn’t there a character in a Wodehouse story with a name like this? I think that shows that, at least in England, it’s seen as pretty darn pretentious.
Cyril Bassington-Bassington. Of course, hsi name was not merely the results of the marriage of a single Bassington to another, but it was the name of some great House of Bassington-Bassingtons, with cadet branches and main lines and what-not.
Wodehouse tended to give hyphenated names to the silliest of characters: so your assumption was probably right, at least for 1920’s England.
There would be a fierce argument, but the man would ultimately prevail, and force her to change her name to Stapleton.
Introducing the Tollemache-Tollemaches.
One member of the family received the name Leone Sextus Denys Oswolf Fraudatifilius Tollemache-Tollemache de Orellana Plantagenet Tollemache-Tollemache, but is said to have gone by Leone Sextus Tollemache (probably after being asked “How many Tollemache’s is that?” one too many times).
This name originated not with a mother who was a pretentious twat, but with a father who was a nutter and married his cousin.
My Grandmother was born a Sibley and married a Sibley. She chose to keep her maiden name, a brave move in the 30’s! 
There are also Cave-Browne-Caves, apparently.
My Aunt’s middle name was (to use a previous example) Sara Burns Mason, she married Mr Burns and is now Sara Burns Mason Burns. Causes endless confusion when she has to sign official documents, especially since the real names are so long she usually runs out of room.
I remember a sitcom where the woman introduced herself as Mrs. Jones-Jones. I can’t remember what show, but this was back in the late 80s or early 90s.
I remember reading a book or story about a child named Sylvia Smythe-Smythe.
Don’t forget Vivian Smith-Smythe-Smith, one of the Upperclass Twits of the Year!
