Who is Sheshbazzar? Is he the same person as Zerubabbel?

The Bible says: >KJV Ezra 1:8 Even those did Cyrus king of Persia bring forth by the hand of Mithredath the treasurer, and numbered them unto Sheshbazzar, the prince of Judah. But in the following chapters that name scarcely turns up. Instead Zerubabbel is portrayed as the prince of Judah in the place of Sheshbazzar. Are they the same people with two names? I would like an answer from biblical and historical sources.
