Historian Eric Plunkett will discuss “The Books that Made Mission San Juan Capistrano,” at the next meeting of the Orange County Historical Society: March 12, 2026, 7:30 p.m., at Trinity Episcopal Church, 2400 N. Canal St., in Orange. Please join us!

Few know that the first library in Orange County – assembled by the padres of Mission San Juan Capistrano themselves – remains among the mission’s collection. Annotations in some of the books tie them to some of the most important missionaries and events in the history of California and tell a fascinating story about how the mission was built, organized, and maintained. These very books were sources used in some of the earliest agricultural, ranching, and architectural developments in the county. Some are directly tied to the most important events in early California. Come hear the story of this library, its books, and how it helped shape our history.

Eric Plunkett is the author of St. Junípero Serra and the Founders of Mission San Juan Capistrano and Orange County and many scholarly articles and is co-author, with Phil Brigandi, of the OCHS publication, The Portola Expedition in Orange County. Plunkett teaches in the Placentia Yorba-Linda Unified School District. A native of Placentia, he graduated with a degree in history from CSU Fullerton. He has led numerous OCHS tours and History Hikes and has addressed OCHS on many occasions. He blogs about the early history of Orange County at www.visionsofcalifornia.blogspot.com.

We look forward to seeing you on Thursday, March 12, 2026 at 7:30pm for this informative presentation! The public is welcome!!!!

The history of Orange County’s Korean-American community will be the subject of guest speaker Ellen Ahn of the Korean American Center and Korean Community Services at the next meeting of the Orange County Historical Society on, February 12, 2026, 7:30 p.m., at Trinity Episcopal Church, 2400 N. Canal St., in Orange. The public is welcome!!

Ahn will trace the Korean-American community from the early 20th-century labor migration to Hawai‘i, through the transformative impact of the 1965 Immigration Act, and into the establishment of Southern California as a primary gateway for Korean immigrants, with O.C. becoming a destination. She’ll tell how the 1992 L.A. riots accelerated suburban migration and reshaped Orange County into a center of Korean-American life with strong institutions, businesses, and more. In the following decades, O.C. developed into a mature, multi generational Korean-American hub characterized by professional leadership, political engagement, and ties to South Korea. Today, O.C. is one of the largest Korean-American population centers in the U.S., marked by high education, strong entrepreneurship, significant Limited English Proficiency needs among seniors, and growing second- and third-generation communities.

A Fullerton resident for over 20 years, Ellen Ahn is the longtime Executive Director of Korean Community Services (KCS), which provides free health, educational, immigration, legal and social service programs to some 10,000 low-income people in Orange County annually.

Ahn grew up in Echo Park’s Koreatown, the child of immigrants. Her father, an Episcopal priest, led a small Korean congregation which started KCS in 1977. Ahn attended both Yale and Georgetown University law school, and later joined the board of KCS. She went back for a master’s in social work from USC to better guide the Buena Park-based nonprofit.

The Korean American Center was founded in 2015 in Irvine, to reclaim what was lost to assimilation: Korean language, culture, and history. In 2018, the Center merged with KCS and was designated a King Sejong Institute – a global network supported by South Korea’s Ministry of Culture, Sports and Tourism to promote Korean language and culture worldwide.

We look forward to learning about the history of Orange County’s Korean-American community from Ellen Ahn of the Korean American Center and Korean Community Services at the next meeting of the Orange County Historical Society on, February 12, 2026, 7:30 p.m., at Trinity Episcopal Church, 2400 N. Canal St., in Orange. The public is welcome!!

Canal St., in Orange. The public is welcome!

In this illustrated lecture, the origins, growth, and eventual breakup of the Moulton Ranch operations will be brought to life, from the sheep herding beginnings to the cattle-raising end. Along the way, you’ll gain insights into the personality and character of Lewis Moulton and Nellie Gail Moulton, two pioneers of Orange County history, and their interactions with historical figures like James Irvine, Judge Richard Egan, and artist Edgar Payne. Come hear how the story of the Moulton Ranch influenced the development of Laguna Niguel, Laguna Hills, Aliso Viejo, Laguna Beach, Dana Point, and Mission Viejo.

Jared Mathis is the President of the Moulton Family Foundation, and a leader in the cultural and education ecosystem of South Orange County. He was recently awarded the Madame Modjeska Visionary Leadership award from ArtsOC for his many philanthropic endeavors. His efforts uphold the family legacy of Lewis and Nellie Gail Moulton; he is one of their great-grandchildren and along with the rest of his family, actively supports the preservation of history and art in South Orange County, including the ranching heritage. He grew up on a ranch outside of Sacramento and has been in the commercial real estate field for most of his professional life.

A graduate of Mission Viejo High School, Dr. Elisabeth Lange went on to earn a PhD in Scandinavian Languages and Literature from U.C. Berkeley. She has been working in the museum field for over 30 years, first as a curator of an exhibition about the Vikings, then at a Scandinavian heritage museum in the Pacific Northwest, before focusing on local history museums. She became the Executive Director of the Moulton Museum in May of 2024, and is excited to be contributing to her hometown area historical awareness and preservation efforts.
