Between 46 and 48, Tiberias Alexander, who succeeded Fadus, ordained the crucification of the two sons of Juda of Gamala: Simon and James.
But Judas the Galilean was an invention of Josephus, per this article:
Recently I was posting about my doubts concerning the evidence for Jewish messianic movements prior to the First Jewish War (66-73 CE) and Giuseppe alerted us to a study by James S. McLaren in Negotiating Diaspora: Jewish Strategies in the Roman Empire. McLaren’s chapter is “Constructing Judaean History in the Diaspora: Josephus’s Accounts of Judas“, pages 90-107.

Hence, if Simon and James were not the sons of Judas the Galilean (since Judas the Galilean never existed) then they were more probably the sons/heirs of Messiah Theudas.
I.e. the sons of Zebedee/Dositheus/John "the Baptist".
