Here's what happened to Princess Eugenie
"Princess Eugenie, her husband Jack Brooksbank, and their son August, had been living at Frogmore Cottage since Meghan Markle and Prince Harry (who lease the home!) left the United Kingdom. But, apparently, Eugenie and Jack quietly relocated this past summer, choosing Nottingham Cottage as their new royal residence. (FYI, they're also spending part of their time in Portugal for Jack's job.) Furthermore,Nottingham Cottage (an ultra-cozy two bedroom) is situated on the Kensington Palace grounds, and also has a connection to the Sussexes"
Personally I would have never left Frogmore for Nottingham on Kensington Palace grounds due to it's connection to the Sussexes!!!
