Succession
As with other Spanish noble titles, the dukedom of Luna descended according to cognatic primogeniture, meaning that females could inherit the title if they had no brothers (or if their brothers had no issue). That changed in 2006, since when the eldest child (regardless of gender) automatically succeeds to noble family titles.
