Eusorus

In Greek mythology, Eusorus (Greek: Εὐσώρου) was the father of Acamas (one of the participants of Trojan War), Aenete (mother of Cyzicus by Aeneus) and also others say of Cyzicus (otherwise his grandson through Aenete).

Eusorus only appeared in various stories as the father of certain figures otherwise he has no myth of his own:

"A period of nine years having elapsed, allies came to join the Trojans: surrounding cities,...Acamas, son of Eusorus..."

"And about the isthmus and the plain the Doliones had their dwelling, and over them Cyzicus son of Aeneus was king, whom Aenete the daughter of goodly Eusorus bare."

"Cyzicus, son of Eusorus, king in an island of the Propontis, received the Argonauts with generous hospitality"
