Was viewing an article, which mention the addition of Miss Lilibeth M-W to the royal line of succession. Since the line of succession has modified with those born either male or female from those descendants of HRH, Prince of Wales.. I found as per attachment, Master Lucas Tindall listed below his sister, Miss Lena Tindall and same with Mr Peter Phillips children.
I didn't realise it was to effect all descendants of Queen Elizabeth II, but not amending HRH, The Princess Royal after the Duke of Sussex, being older then the Duke of York.
