One royal fan commented, “Her name is NOT Meghan Sussex. Her name is technically Rachel Mountbatten-Windsor. Sussex is a county in England & part of a courtesy title – NOT her last name.”

Another added, “So who criticizes a guest like that? And her last name is not Sussex. Wouldn’t it be Mountbatten-Windsor?”

A third wrote, “‘Duchess of Sussex’ is a courtesy title she holds only through her marriage. It is not her surname, and I’m quite sure she doesn’t have ‘Meghan Sussex’ on her California driver’s license. Legally, her last name should be Mountbatten-Windsor.”

Meghan’s father, Thomas Markle, also voiced his disappointment, saying her move away from the Markle name would have upset his late mother.

“My mum loved Meghan very much but she would be so disappointed to hear that Meghan no longer wants to use the name ‘Markle,’” he said. “My mother was proud to be a Markle. So am I.”
