When Princess Charlotte was born, Elizabeth was one of Will and Kate’s first visitors. Even Prince George is very fond of his great grandmother and has a special and adorable name for her — “Gan-Gan”. According to 34-year-old Kate, her most memorable engagement with the queen was an “away day.”

She went with Elizabeth and Prince Philip for a day out in Leicester as part of the Diamond Jubilee tour in 2012. She revealed as William was away, Elizabeth took time to make sure she was happy and looked after. Kate added it showed the queen loved her family.

According to Sophie, Countess of Wessex, Elizabeth wore bright colors so people could spot her from far. Her passion for horses is well known and still rides. She is an avid horse-racing fan and breeds them too. Camilla, the Duchess of Cornwall said Elizabeth’s love for horses is a two-way affection.

Interestingly, the queen played “catching happy days” with her cousin Margaret Rhodes as a child. However, Rhodes said Elizabeth was very much an ordinary little girl, but she was always a slightly serious little girl. Besides, the family resoundingly agreed that one of the keys to the queen’s successful long reign is her relationship with her husband, Prince Philip.
