Kate Rothschild

Eldest sibling Kate, was, weirdly enough, formerly married to Ben Goldsmith, the brother of Alice's husband, Zac. Just rich people things. They split in 2012 and the heiress is currently with entrepreneur boyfriend Paul Forkan - the pair recently welcomed a baby boy. Unfortunately, Kate experienced tragedy when her and Ben's 15-year-old daughter Iris died in an accident in 2019. To honor her memory, Kate helped launch The Iris Project, "a global community of young people working to protect and restore their local natural environment."
