[1] The origin of the name is unknown; daimon means "demon", but may, according to Haris Kalligas, possibly refer to the site of Daimonia at Cape Maleas near Monemvasia.
In the popular language, it became Daimonogiannes (Δαιμονογιάννης), as it is found in the Chronicle of the Morea, and variously Demonozaneus, Demonozannes, and de Mon[o]ianis in Western sources.
[2] From the outset the family were mostly associated with the fortress city of Monemvasia and the wider southern Peloponnese, while others were active in the island of Kythira off the Peloponnesian coast and in Venetian-ruled Crete, and a few as far afield as Venice itself, Serres, Constantinople, or the Kingdom of Naples.
[4] The family also ruled Kythira, beginning perhaps as early as the 12th century, until 1238, when it passed to the Venetian House of Venier.
He was followed by other notable historians like Du Cange and Girolamo Muzio, while the 18th-century writers Niccolò Comneno Papadopoli and Flaminius Cornelius recorded that the noted scholar Andreas Eudaimonoioannes descended from the Palaiologoi.
