One of Xenia's descendants would currently be the Head of the Romanov Family, but all of her children married morganatically, thus Grand Duchess Maria Vladimirovna currently holds that position.

Following the revolution Xenia and her husband separated. She became a dependent of the British Royal family who in addition to an income, granted her a grace and favour house first in Windsor Great Park and then in the grounds of Hampton Court Palace, London.
