But prior to their wedding days, the sisters were known as Princess Beatrice of York and Princess Eugenie of York, to reflect their father’s title.
Eugenie’s baby is not entitled to the York dukedom, due to royal convention.
Princess Eugenie and her older sister Princess Beatrice are not eligible to inherit their father’s dukedom.
Royal titles are passed through the male line, and as Prince Andrew has two daughters and no sons, the title will be left vacant when he dies.
Therefore the title will not pass to Eugenie’s child, nor any future children Beatrice and Eugenie may have.
