Elizaphan ♂ also known as Elzaphan
The NIV translation has two separate people Elizaphan and Elzaphan both sons of Uzziel. Both Uzziel's have to be Korahithes and both are around the same generation. So they almost clearly are the same person. Additionally, the German Luther uses "Elizafan" all the time.
All this leads me to the conclusion, that this is in fact one and the same person.
