"Growing up in South Africa, I really had very little idea of how significant she was in the world until I was much older." Eliza added that Princess Diana was "incredibly warm, maternal and loving. She always made an effort to connect with us as children and had a talent for reading children's hearts." Princess Diana.

"Obviously it could have been quite terrifying for us, being so young and not understanding what was happening. But she turned it into a game of who could get back to the car first. It was amazing how she protected us in a way that made us feel safe and not frightened," Eliza said. "We had no idea what she was doing at the time." Can't get enough of PEOPLE's Royals coverage?
