Multiple user accounts created after Migration Assistant hangs

[Gregrb]

I had a problem with migration assistant hanging with out completing when going from external drive time machine to new mac. I had to force quit and it seemed to not have worked, I now finally got it to complete but have found that Multiple user accounts have been created. I know which one is the correct one to use, so how do I remove all the other user accounts start from the correct one, and remove all potential duplicates of files etc that will have been created?

Is there a reason you cannot remove them from the Users & Groups setting panel?
