Antigone was the daughter and the second child of Berenice, a noblewoman from Eordeaea,[3] and her first husband Philip.
[3] Berenice's mother was the niece of the powerful regent Antipater[4] and was related to members of the Argead dynasty.
[6] Based on Plutarch (Pyrrhus 4.4), her father was previously married and had children, including daughters.
[10][11] Pyrrhus obtained a fleet of ships and funding from Ptolemy I and set sail with Antigone for his kingdom in Epirus.
[14] As a posthumous honour to his first wife, Pyrrhus founded a colony called Antigonia, which he named after her.
