Miss Maudie Atkinson went by "Maudie" as her first name. Maudie is most likely a nickname for "Maud" or "Maude." The name Maude can also be short for Mathilda. Maude was a popular name for girls in the late 1800s, which was when Miss Maudie Atkinson was born.
Miss Maudie Atkinson was Scout and Jem's neighbor, who lived "across the street one door down." She was kind to Scout and Jem, and because of this they "always enjoyed the free run of Miss Maudie’s yard if [they] kept out of her azaleas." Scout became especially close to Miss Maudie. She felt comfortable talking to the older lady and she could ask her questions. Scout once told Miss Maudie that she was "the best lady" she knew.
Her welcoming warmth and compassion toward others made Miss Maudie a fairly important character in To Kill a Mockingbird. She was a longtime friend of the Finch family. She had grown up with Atticus Finch and his family at Finch's Landing, where she had been their neighbor. Miss Maudie was especially close to Atticus's younger brother, Jack, because they were close in age. He often joked that he wanted to marry her.
Her full name is Miss Maudie Atkinson, so, her first name is actually Maudie. Oftentimes, calling an adult female by Miss or Ms. followed by her first name is an acceptable familiar, yet respectable, title for children.
Hope this helps!
