Answer the following question: What is the full name of the person that is overjoyed that Beatrix Potter is a spinster?  Answer the above question based on the context below:  The story begins with Beatrix Potter nervously packing her portfolio and narrating that she is a London spinster, and that her ambition to become a children's author meets with wide disapproval. She and her chaperone, Miss Wiggin, visit the publishing house of Harold and Fruing Warne, who decide to publish her book. Beatrix is thrilled and returns home, taking a drive through the parks to celebrate first. However, it is revealed the Warne brothers think her book is ridiculous and will no doubt be a failure. The only reason they agreed to publish it is because they promised their younger brother, Norman, a project. When Norman Warne visits Beatrix, they make decisions about her book regarding size, colour and price. Norman admits he has never done anything like this before but has given her book a great deal of thought. Beatrix realises what Norman's brothers have done regarding him and her, but they become determined to prove them wrong. Norman takes Beatrix to the printer, and she has her drawings reproduced and copies of her book sold. Thrilled, Beatrix and Norman visit the Warne family, where Beatrix meets the wheelchair-bound but lovely Mrs. Warne, and Norman's sister, Amelia, nicknamed "Millie". Millie has decided that she and Beatrix are going to be friends and is overjoyed that Beatrix is a spinster, as is Millie, who believes men to be nothing but bores. The family befriends Beatrix, yet Helen Potter, Beatrix's social-climbing mother, is unhappy about her daughter spending time in the company of 'tradesmen'.
Answer:
Amelia
