Lady Rose Gilman
Rose Gilman nee Windsor is the daughter of the Duke and Duchess of Gloucester. Gilman stays away from the royalty spotlight, and instead, she focuses on her career as a producer for popular filmmakers. She is worth about $5 million, and some of that came from her work on the Harry Potter films, as well as the Margaret Thatcher biopic that she helped produce.
Lady Gabriella Windsor
Gabriella is Lord Frederick's sister, and she is also extremely wealthy and successful, just like him. She worked as a journalist, using the royal pipeline to help fund her stories. With the work she has done in the journalism field, as well as the cash that she got by simply being a royal family member, she has amassed roughly $40 million.
