Neleides or Nelides (/ˈniːliɪdz/ NEEL-ee-idz (Nηλείδης); also Neleiades (Νηληιάδης), Neleius, and in the plural Neleidae; Greek: Νηλεῖδαι) was a patronymic of ancient Greece derived from Neleus, son of the Greek god Poseidon, and was used to refer to his descendants.[1] In literature, this name typically designated either Nestor, the son of Neleus, or Antilochus, his grandson.[2][3][4] One notable offshoot of this family line was the Alcmaeonidae.[5]
