Let's find out more things about Christina Nillson, the main influence for Christine Daae.
I'll show you experts from other websites, which talk about her life with details, better than I could've ever written it. I will add some things to compare her with Christine Daae.
Christina Nilsson, soprano (1843 - 1921) with her golden voice made no less than four major tours across the United States and Canada. She was born on August 20, 1843, as the youngest of seven children at the small farm of Snugge, just south of Växjö in Småland. Snugge had been in Christina's family's possession for generations, but during her adolescence they were forced to give it up, as one of many bitter steps they had to climb down the social ladder. They came to belong to the large group of really poor Swedes in the 1800s, a period when many people emigrated to the United States.
Christine Daae: Her father owned a farm, but had to give it up. She was an only child.
Christina Nilsson: She early showed a talent for singing as well as playing the violin. She was only eight years old when she started to contribute to her own and her family's support. Rather like a little beggar girl of the country road she made for the dances, the inns, the markets and other places where people gathered. With her song, her violin and her jaunty performance she became famous in the vicinity.
Christine Daae: She didn't play the violin, although she was a beautiful singer.
Christina Nilsson: When she, at the age of fourteen, attended the summer fair in Ljungby she got a fantastic opportunity which was going to change her life forever. She was offered a musical education by a local celebrity who had fallen for her obvious musical aptitude, and she accepted it greatfully.
Christine Daae: She was discovered by a singing teacher and his wife.
She died in 1921. Christine Daae's death is never mentioned.
