'Very old' human remains have been found near Prince Harry and Meghan Markle's Santa Barbara home

• Human remains were found at an estate 350 yards from Meghan and Harry's property.
• The bones were thought to belong to a young adult from the Chumash tribe dating back centuries.
• The sheriff's office said a forensic anthropologist would investigate the origins of the remains.

Human bones have been discovered at an estate just 350 yards away from the Duke and Duchess of Sussex's home in California's Santa Barbara County, The Sun reports.

The bones, which were found during landscaping construction in soil 2 to 3 feet deep on May 24, appeared to belong to a "young adult" and were "very old," a representative for the Santa Barbara County Sheriff's Office told the Mail Online.

The reports say the remains may belong to a member of the Chumash tribe, a group of Native Americans who historically inhabited central and southern coastal regions of California.

A representative for the sheriff's office told the Mail Online that the bones' origin would be confirmed only after a forensic anthropologist investigated but that they were most likely Chumash "because we live in that area."

The Chumash people once occupied 7,000 square miles that spanned from Malibu to Paso Robles, as well as the western edge of the San Joaquin Valley, according to the official website for the Santa Ynez Band of Chumash Indians.

The tribe called themselves "the first people" and pointed to the Pacific Ocean as their first home.

Raquel Zick, a sheriff's office representative, told The Sun that an investigation would begin if the remains were found to not be old.

The sheriff's office did tell The Sun that the remains had no connection to Meghan Markle and Prince Harry's property.

The couple moved into the property in July last year after previously living in Tyler Perry's eight-bedroom, 12-bathroom mansion in Beverly Hills.

It's where they will raise their 2-year-old son, Archie, and his younger sister, who is due to be born this summer.
