E. J. (Eusebius Joseph) Molera

Born in 1846 and dying in 1932, E. J. Molera is generally identified in library and archival records as Eusebius Joseph Molera. He is associated with Monterey County and the Cooper-Molera family, a well-known California family whose papers are preserved at The Bancroft Library at the University of California, Berkeley.

Molera is best remembered as co-author, with Zoeth Skinner Eldredge, of The March of Portola and the Discovery of the Bay of San Francisco. That work helped document a key episode in early California history and is still widely available through public-domain library projects.

Archival sources place him within the family that managed Rancho El Sur, and later generations of that family are closely tied to what is now Andrew Molera State Park. Although not a major literary celebrity, he remains a meaningful figure for readers interested in California history, Monterey heritage, and the preservation of early regional narratives.
