Disappearance of Sky Metalwala
Solomon said he believed that his son was alive, but perhaps not in the U.S. In spring of 2011, after the visit to the doctor that was the last independent record of Sky's presence outside of Biryukova's household, he recalled that her estranged father came from Ukraine to visit her. He wondered to the "Weekly" if the older man could have taken the boy back to that country with him at the time. But in 2013, he said that he did not know how that could have happened.
Salome
Salome is mentioned as a stepdaughter of Herod Antipas in Josephus's "Jewish Antiquities" (Book XVIII, Chapter 5, 4):Herodias, [...], was married to Herod, the son of Herod the Great, who was born of Mariamne, the daughter of Simon the high priest, who had a daughter, Salome; after whose birth Herodias took upon her to confound the laws of our country, and divorced herself from her husband while he was alive, and was married to Herod, her husband's brother by the father's side, he was tetrarch of Galilee; but her daughter Salome was married to Philip, the son of Herod, and tetrarch of Trachonitis; and as he died childless, Aristobulus, the son of Herod, the brother of Agrippa, married her; they had three sons, Herod, Agrippa, and Aristobulus;
According to William Smith's "Dictionary of Greek and Roman Antiquities":
A few coins with portraits of Aristobulus and Salome have been found.
