Is Charlie Sean Mexican?

No. He was born in NYC in 1965, and his father, Martin Sheen was born in Dayton, OH.

His grandfather, Francisco Estevez was an immigrant from Spain, while his grandmother was born in Ireland. So he would be a third generation immigrant with both Irish and Spanish ancestry.
