Adrian Grenier is an American actor, producer, director, and musician. He is best known for playing Vincent Chase on the HBO series Entourage.
Grenier was born in Santa Fe, New Mexico, the son of Karesse Grenier and John Dunbar. His parents were never married. He was raised by his mother in New York City. His father was from Ohio, and has English, German, and Irish ancestry. His mother was born in New Mexico, to a family of mostly Mexican , and some French, descent. A DNA test on the series Finding Your Roots showed Grenier to have approximatelypercent Native American ancestry and that his direct matrilineal line is Native American. The program determined that his ancestor Diego de Montoya was the leader of an encomienda, a protectorate of Puebloan peoples in Pueblo San Pedro in New Mexico. This ancestor of Grenier is shared with author and commentator Linda Chavez, making them ninth cousins.
