Samuel Gridley Howe brought many Greek refugee children back with him to the United States to educate them. Two who later gained prominence were John Celivergos Zachos, who became an abolitionist and activist for women's rights, and Christophoros P. Kastanes. Kastanes survived the Chios massacre. He later wrote a memoir about these events, "The Greek Exile, Or, a Narrative of the Captivity and Escape of Christophorus Plato Castanis" (1851). He mentioned both Dr. Howe and John Celivergos Zachos in this book.
