The Cambridge Hebrew Ladies Educational Society was first formed in 1898 for the purpose of teaching the Hebrew language to Jewish children. The society was renamed the Cambridge Hebrew Women's Aid Society in 1914, and reorganized to include a broad range of philanthropic causes, including the care of tubercular patients and provision of Passover food to the needy. The collection contains bound ledgers of meeting minutes from 1914-1969.

Noemi #11 was an organizational branch of the charitable organization United Order True Sisters. The members of Noemi #11 were particularly dedicated to the philanthropic cause of aid to disabled children, and had a strong association with Children’s Hospital, Boston, and Massachusetts General Hospital. The collection includes meeting minutes, personal histories of the lodge, programs, photographs and correspondence.
