Mount Willey is a mountain located in Grafton County, New Hampshire. The mountain is named after Samuel Willey, Jr. (1766–1826) and his family, who in 1825 moved into a house in Crawford Notch. The family was killed a year later in August 1826 during a landslide.
Mount Willey used to have a different name.
It was named after the landslide that killed the family so it was called something else before that. It is something that is inferred so the computer can't identify it.
