After looking at the comments for Doll of the Month suggestions, I decided on Samantha Parkington!
(Edit made by AGDN reader Raine)
In 1904, Samantha lives in Mount Bedford, New York with her Grandmary, but later moves to New York City with her Uncle Gard and Aunt Cornelia.
Samantha is an adventurous well-to-do girl who lives in her Grandmary's mansion after her parents died when she was 5. She enjoys climbing trees and the outdoors, but her life changes when her annoying neighbor Eddie gets a new servant, Nellie O'Malley. Samantha quickly befriends Nellie, which sets off Samantha's journey about learning about the real world and becoming a voice for the less fortunate.
Samantha was released in 1986, retired in 2008, and returned to the historical lineup in 2014.
