- Sissi' Birthday is on Christmas.
- * Sissi is allowed to become the 1st female to ever race- and win- in The official Equestrian race in Austria.
- Born on December 24, 1837.
- In real life Sisi had an older sister named Helene who was supposed to be betrothed to Emperor Franz Joseph as desired by Archduchess Sophie, however upon laying eyes on Sisi, Franz Joseph feel madly in love with her and demanded to marry her over Helene.
- Helena frequently refers to Sisi as a peasant. In fact, Sisi was the grand-daughter of the King of Bavaria and her mother Ludovika was actually the sister of Archduchess Sophie of Austria (Empress Sophia in the series). Therefore Sisi was the cousin of Franz and of much higher rank than the Viscountess Helena.
- Sisi's relationship with Franz Joseph wasn't as romantic as in the show. While Franz Joseph was passionately in love with her, Sisi never fully felt the same way and was emotionally distant from him. She ended up avoiding him and court life as much as she could.
- Sisi was one of ten children of Ludovika and Max, however none of her siblings in the show matched her real siblings. Sisi was the fourth child and second daughter. She had five brothers and four sisters.
