From Kawaiahao Church Newsletter Feb/Mar 2007:
"Walter Francis Frear devoted his life to the community, serving as a First Circuit Court Judge for the Kingdom of Hawaii, Chief Justice for the Territory of Hawaii, and as Governor of the Territory of Hawaii. Chief Justice Frear helped to create many notable civic institutions in Hawaii such as the YMCA, the Social Service Bureau, Palama Settlement, the United Welfare Campaign, the Hawaii Historical Society and the Library of Hawaii.
Mary Dillingham Frear was also a prominent figure in community activities, organizing the YWCA in Hawaii, the College Club of Honolulu, and serving as a Regent for the University of Hawaii. An active member in the Daughters of Hawaii and an accomplished author, Mrs. Frear is fondly remembered as a "talented woman of great kindness and personal charm who had an intense interest in the people of Hawaii and the progress of the community."
The Mary D. and Walter F. Frear Eleemosynary Trust, established in 1934 by Chief Justice and Mrs. Frear to support community service endeavors, stands as a living legacy of their enduring commitment to and love for Hawaii and its people by supporting religious, charitable, educational and literary projects.

August 1, 1893 she married Walter Francis Frear.
