The British Royal Family, to be precise, should be called "the Windsor family".
Because their surname is "Mountbatten-Windsor"!
Take Prince Charles, for example, his full name is "Prince Henry Charles Albert David Mountbatten-Windsor"...
That's how foreign names work; not only do they have a surname, but they also include their father's name, so it's particularly long.
As for the full names of the nobility, they are even longer, because they also include names of their estates, titles, and such.
Ever since the revival of the Romanov family, Rossiyana's name has also become "Grand Duchess Rossiyana Romanov".
Perhaps these royal and noble families intentionally use complicated etiquette and rules to distinguish themselves from commoners...
