In the wake of Zara Tindall’s pregnancy news, constitutional expert Iain MacMarthanne told Express.co.uk: “As a rule, titles do not pass through the female line as royal women are considered to have married out at the time of their marriage.”
“In contrast, titles are passed through the male line in accordance with George V’s Warrant of 1917, and thereafter the terms of creation of any peerage.”
The expert added: “As a result of these rules, the Queen has grandchildren who have both royal titles and none at all, Princess Anne’s children, Peter and Zara, being an example of the latter.”
Mr Macmarthanne explained while William can pass on any royal titles, his female cousins including Beatrice and Eugenie are unable to do so.
