Although Mary Amelia Ingalls' character in the "Little House on the Prairie" television series married Adam Kendall, Ingalls never married in the books or in real life.
According to Laura Ingalls Wilder Historic Homes, Ingalls graduated from a school for the blind in Vinton, Iowa, and then moved in with her parents in a home on Third Street in De Smet, South Dakota. She continued to live there with her mother after her father died. After her mother passed away she visited her sister Carrie in Keystone, South Dakota, where she suffered a stroke. Ingalls died in 1928 at the age of 63 and is buried in the De Smet cemetery.
