HT4796 How to solve my situation of having several Mac users created for me as I used Migration Assistant multiple times to move files from my PC

Question

I recently tried to migrate data from my old and perpetually unstable PC to my new iMac through the Set up Assistant.  However, half way through the 6 hour process, my PC crashed (the exact reason why I finally bought a Mac!) and the connection was lost. I continued with the Mac set up and then tried again later to migrate the files with Migration Assistant.  Since I was nervous that my PC would crash again, I decided to do the data transfer in multiple migrations (ie. first I did photos and then after seeing that that was done successfully I did music and so on).  Unexpected to me, even though all of the 4 migrations were successful I now have 4 additional users (in addition to the one I set up durnig the initial process) because each migration created a new user.  Each user has  little bits of my data. 
What is the easiest way to merge these users or at least the data that resides in each one?  I really only want one user.  thank you.

You may not have created a mess, it's possible you simply don't know where your data is after migrating. Had you followed the Setup Assistant's on-screen prompts when you initially turned on your new system you would be running just fine by now. My guess is you haven't been exposed to Pondini's Lion Setup Assistant tips.
Migration Assistant (MA) and Setup Assistant (SA) are cousins, similar but different. The primary difference is MA creates a new user account which can be confusing to some users. If you successfuly migrated then log out of your existing using account and you should see the new user account. Log into that account then you should see the migrated data. If you do then use Pondini's Transferring files from one User Account to another.
However if you have totally made of mess out of things then I'd start over, this time using the Setup Assistant Tips beginning where he discusses Second Chance.
