Baptised more than one? Or Not?

As far as I am aware, the only mention of re-baptism in the New Testament occurred in Acts 19:1-7, where approximately twelve individuals who had received only the baptism of repentance (such as that preached and performed by John the Baptist) were re-baptized in the name of Jesus, and then received the Holy Spirit through the laying on of hands by Paul, after which they spoke in tongues and prophesied as evidence of the Holy Spirit's presence. This would lead me to believe that (although re-baptism is not prohibited), as long as a person has been baptized either in the name of Jesus (as in Acts 19), or in the name of the Father, the Son, and the Holy Spirit (as mentioned by Jesus in Matthew 28:19), there would be no requirement based on Scripture to be re-baptized.
