Josephus ., Jr.

‘..three men named Joseph, one the brother of Antipatros and Herod’s uncle who became Salome’s husband, the second a son of Antipatros and Herod’s brother, and the third the son of Herod’s brother Joseph, who married Olympias, daughter of Herod and Malthace the Samaritan. ' from 'Jews, Idumaeans, and ancient Arabs: relations of the Jews in Eretz-Israel with the nations of the frontier and the desert during the Hellenistic and Roman era (332 BCE-70 CE)' by Aryeh Kasher

Please see Discussion about whether this man's father was Herod's Uncle Joseph (who married his niece Salome I); or Herod's brother Joseph. And whether he then had a brother called Antipater by Uncle Joseph & Salome. (As Wagner, Sir Anthony Richard; ‘Pedigree and Progress: Essays in the Genealogical Interpretation of History’ suggests. Most other sources do not, though.) [Sharon April 2012]
