Hawaiian Mission Children's Society

Hawaiian Mission Children's Society (acronym, HMCS; sometimes abbreviated as Mission Children's Society; common name, Cousins' Society; originally, Social Missionary Society; est. 1852) is an American historical and memorial society of descendants of Protestant missionaries associated with the American Board of Commissioners for Foreign Missions (ABCFM) to the Hawaiian Kingdom. It was founded in Honolulu in 1852. At that time, the Hawaiian Islands had been largely evangelized. The families of the missionaries were rapidly growing up around them. Many of the older children had been sent to the U.S. for further advantages in education. The foreign community outside of the missionary circle was small, and all social and literary advantages centered in missionary families. Incorporated in 1907, in 1920, it established the Hawaiian Mission Houses Historic Site and Archives.
