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.{{sfn|Charalambakis|2010|pp=174–176}} It is unclear whether all the bearers of the family name were members of the same family, and it has been suggested that there existed two closely related families with the same name, one in the Peloponnese and one in Crete. However, as the family first appears in the Peloponnese and Kythira, and only from the 16th century on occurs frequently in Crete (with 25 family members in the 16th century alone), it is more likely that the family moved to the island then, with the bulk of the family probably abandoning Monemvasia for Crete in 1545.{{sfn|Charalambakis|2010|pp=175–177}} The family also ruled Kythira, beginning perhaps as early as the 12th century, until 1238, when it passed to the Venetian House of Venier.{{sfn|Charalambakis|2010|pp=175–176 (esp. note 7)}} The family remained active in the island thereafter, at least up to the mid-16th century.{{sfn|Charalambakis|2010|pp=177–178}}
Later scholars from the 16th to 18th centuries, linked the family to the last Byzantine imperial dynasty of the Palaiologoi. The 16th-century scholar Francesco Sansovino wrote that a certain John Palaiologos received the sobriquet "Eudaimonoioannes", i.e. "Fortunate John", for his exploits. 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. In so far as can be determined by modern research, however, the two families were unrelated except for a single marriage; Sansovino's account may be a later invention by the family itself, as the form "Eudaimonoioannes" does not appear until near the middle of the 14th century.{{sfn|Charalambakis|2010|pp=178–179}} They did intermarry however with other noble families, as indicated by the occurrence of double surnames containing the family names Komnenos, Sarantenos, Notaras, Akatzas, Sophianos, and Komes alongside that of Daimonoioannes/Eudaimonoiannes.{{sfn|Charalambakis|2010|pp=182–183}}
