History
Both her parents, aunt and uncle had troubles getting children. So they went to the Northern Mountains and the Rock Trolls. The trolls turned the two woman pregnant with the power of ice. That's why both girls would eventually have ice magic. The trolls warned them that when the two babies would reach adulthood, two other adults would die.

Shortly after, the queen got very ill. The magic of a sunflower healed her and it resulted in Rapunzels change of powers. Instead of ice magic, Rapunzel had healing and age-turning hair. The King and Queen lighted a lantern on her birthday, but that night, Rapunzel was taken by Gothel.

Gothel raised Rapunzel as her own in a secret tower (and secretly used her healing abbility to stay young forever) for 18 years, untill Eugene Fitzherbert rescued her from the now crazy and life threatening Gothel. Gothel died while trying to kill Rapunzel, and Rapunzel was returned home to her parents.

Marriage
Rapunzel married Eugene Fitzherbert the same year. Her aunt and uncle tried to attend but died on their way there. Since Queen Elsa and Rapunzel reached adulthood that moment, it is most likely they are the lives that were taken because of Elsa's abilities.
