There are a few instances where aunts are mentioned, but they are not central figures:
* In "The Tale of Mrs. Tiggy-Winkle," the hedgehog, Mrs. Tiggy-Winkle, is mentioned to have an "Aunt Tabitha," who is also a washerwoman. However, Aunt Tabitha never appears in the story.
* In "The Tale of Peter Rabbit," Peter's mother warns him not to go into Mr. McGregor's garden, saying that his father was caught there and "turned into a pie by Mrs. McGregor." This could be interpreted as Mrs. McGregor being an aunt-like figure to Peter, though it's never explicitly stated.
It's important to remember that Potter's stories are primarily focused on the adventures and interactions of her animal characters. While human characters exist, they often serve as a backdrop or catalyst for the animal protagonists.
