(AP) — A cemetery where residents of a Nebraska home for the mentally ill were buried anonymously is being renovated as part of a Lincoln teen’s Eagle Scout project.

15-year-old Ethan Cecava organized Saturday’s excavations at the Calvert Street Cemetery to uncover forgotten grave markers.

Cecava also put together a map and built a kiosk to help family members find where loved ones were buried from 1872 to 1927.

Cecava picked the Calvert Street Cemetery after reading news stories about how 467 people had been buried there anonymously.

It wasn’t until a 2009 Nebraska Supreme Court ruling that the state’s mental hospitals were allowed to release the names of people buried in their cemeteries.
