Caroline and Charlotte were also trained by their father Christian and nurtured by their mother Lele. Caroline does not seem to play much sport like her older brother Casper but Charlotte has started climbing the ranks in tennis. 

Similarly, Charlotte does not seem to be performing well in terms of her tennis, but it is only her start, as she shall climb ranks through the guidance of her brother and father. 

Moreover, Charlotte is likely to be completing her high school soon, she shall also join the university in near time as well as participate as an athlete in competitions. 

Caroline seems to be older than Charlotte thus it is likely that she has already joined university and continuing her studies in her passionate field. 

Caroline seems to be nonchalant about her dating life, as she often posts her personal affection for her partner on Instagram.

She was dating Joachim Hermansen, a Norwegian Hockey player but her current relationship status has not been disclosed.  She is likely to be in her late teens or early 20s. 

Moreover, Caroline seems to be frank and outgoing, while Charlotte is reserved and is a private person. Despite the contrast in their personalities, both of them seem to share a happy and cognizant bond in their relationship. 

Moreover, Charlotte's dating life is a mystery, she has just turned 16 years old, and she has participated in the international competition of J4 and J5 girls in singles, but has lost both of the matches. 

Nonetheless, she is unlikely to discourage, with the insight and help from her supportive brother, she shall improve her game and achieve newer records in her next competition.
