"Un Village Cycladien Chora d'Amorgos" by Emil Kolodny

"Un Village Cycladien Chora d'Amorgos" by Emil Kolodny and is written in French.  the book is packed with information about Amorgos, and especially families in the Chora.  The book was unavailable on Amazon when I checked.  You may have more success with French book websites, such as Chapitre.
