I'm sorry if this is posted elsewhere, but I have been unable to find the post (admittedly I haven't read through the many, many posts shared in this and other threads).
If Eugenie and Beatrice have children before Charles becomes King, will they be legible for a royal title, given that Eug and Bea are children of male line descendants to the throne? I am unsure as Edo and Jack have not become Royal Dukes nor Earls and the position in line to the throne for the princesses are somewhat down the line, and ofc the fact they are princesses rather than princes may inhibit them.
I cant think of any recent examples bar Margaret, whose husband was made an Earl at their wedding, and Princess Mary who became Countess Lascelles upon her marriage, though I am sure you on this board will politely remind me! I am all too familiar with the acquiring of titles in the Swedish Royal Family and find the BRF a confusing one to understand!
Their kids won’t have royal titles. It only passes through male line descendants. Furthermore, the royal titles end with the monarch’s male-line grandchildren. The monarch’s male line great grandchildren are entitled to be known by their father’s courtesy title (ie once James, Viscount Severn becomes Earl of Wessex his son, a great-grandchild, will be known by courtesy as Viscount Severn, as it’s his fathers second highest title). If their father does not have a courtesy title then they are entitled to the rank of the daughters/younger sons of a Duke (Lady/Lord). For example Prince Michael of Kent has no Dukedom, he’s a male line grandchild of a king and his children are known as Lord Frederick Windsor and Lady Gabriella Windsor.
The titles can’t pass through a female unfortunately. Their husbands would have to have received a title as Margaret’s husband did. This was typical before but after Anne is no longer. Both Princess Alexandra and Princess Anne’s husbands refused titles. I doubt they were offered to Bea or Eug’s husbands.
It is possible the EII could make the Dukedom of York heritable by female progeny. However, I believe this would require a second creation by the Queen for Prince Andrew and given everything going on with him I doubt that will happen.
Bea’s kids technically will have the title of count, only via courtesy and via Edo. But seeing as it’s not recognized in the U.K./Italy and that Edo does not use his title, I doubt their children will use it. But they are from a comital house.
