Aeacides

In Greek mythology, the descendants or sons of Aeacus, particularly referring to the hero Achilles and his relatives through the family line.

From Greek Aiacos (Αἴακος) + -ides (suffix meaning 'son of' or 'descendant of'). The -ides suffix is fundamental in Greek genealogy and was adopted into English to describe mythological family lines and dynastic relationships.
