There's a new article about John the Baptist (not sure why they reverted to Baptist instead of the modern English 'baptizer'), and it goes into several areas of his life followed by quotes from Josephus showing that these specific things were historically documented. The article is summarized by saying:
The first-century historian Josephus viewed John the Baptist as a real person. So can we.
That's the thrust of the whole article. If it's good enough for Josephus, it's good enough for us.
Fun fact: Josephus also said that Jesus was killed on a cross, that the proper name of God was not being used in Jesus time, and that Jerusalem's desolation lasted 50 years instead of 70, destroying 607 and therefore 1914.
Now what say you?
