Aaron Pico is a seventh-generation Californio and a documented great-great-great-great-grandson of Pío Pico, the last Mexican governor of Alta California — a genealogical detail that’s rare in modern professional sports. It also ties him, at least by lineage, to a historically prominent Catholic Californio family. But when it comes to Pico’s own, personal religious practice today, the public record is much thinner than the family history suggests.
| Full Name | Aaron Pico |
| Sport | Mixed martial arts (Bellator; formerly elite amateur wrestler) |
| High School | St. John Bosco High School (Catholic, Salesian-run), Bellflower, CA |
| Notable Ancestry | Great-great-great-great-grandson of Pío Pico, last Mexican governor of Alta California |
| Religion | Not personally confirmed; circumstantial signals point toward a Catholic-associated background |
What’s Actually Confirmed — and What Isn’t
Pico attended St. John Bosco High School, a Catholic school in Bellflower, California, where he went 42-0 as a freshman wrestler on his way to a CIF state title. In January 2018, MMA Junkie published a fight-day feature on Pico that referenced church as part of his pre-fight routine at the time. Those are real, sourced details — but neither one is Pico personally stating his religion in an interview, and no mainstream outlet has him doing so. Some low-quality aggregator sites flatly label him “Catholic” without citing any interview or statement, which doesn’t meet a real sourcing bar and shouldn’t be treated as confirmed fact.
A Seventh-Generation Californio
Genealogical records trace Pico’s ancestry back to Pío Pico, the last governor of Alta California under Mexican rule — a lineage tied to one of California’s most historically significant Catholic families. It’s a striking piece of family history, though it describes ancestry rather than Pico’s own current religious practice, which he hasn’t discussed on the record.
From Undefeated Wrestler to MMA Prospect
Before turning pro in MMA at 18, Pico was considered one of the most dominant amateur wrestlers of his generation, going undefeated through high school. ESPN once called him a candidate for the “greatest prospect in MMA history.” None of that career coverage has touched on his personal faith in detail.

Yes — genealogical sources document him as a descendant of Pío Pico, the last Mexican governor of Alta California.
