By all means. Remember, there are no stupid questions.
In which body of water was the above mentioned individual baptized?
None. I was under the impression that the event happened before Jesus returned and sent out the Apostles to baptise the nations. So any "requirement" of baptism would not have been in effect at the time.
Not that a merciful God would hold that against someone who had no physical possibility of being baptised anyway. God is not a legalist without compassion.

Ohhhh! I see. Christ added baptism above and beyond the need for faith. Got it.
