Admin issues

[SeeDub]

i just obtained a hand-me-down iMac that I installed Snow Leopard on. I then ran an update and upgraded to El Capitan. This is my second go 'round with this and I am hoping to get an answer to a question before it comes up (again.). I will be using the Migration Assistant to bring over the data from my old Windows PC. The last time I did this, it created a second account with my name, which was also listed as Admin, and I could not find any of my data. What am I doing wrong?
The reason this is the second try is that I thought if I Migrated my info during setup, I'd end up with just one user. Sadly, migrating from a PC to a Mac is not an option. Fine.
1. Is there harm in having two "Catherine-admin" accounts?
2. Does it make a difference which apps/programs I use on either user?
3. Where will all of my PC data move to on my Mac? (Photos were not in the Photos app, there were no files with my docs and spreadsheets. The only things I could see were the docs that started on my PC desktop which were now on my Msc desktop.) I thought something bad happened during migration so I started over.

This may not be of help, but I'll make a suggestion anyway. You may have already tried this.

Sometimes, things may work better if you skip using Migration Assistant, and just do a "manual migration".

I would try copying all the files I wanted to bring over (from the PC side) onto an external hard drive.

Then, connect the drive to the new Mac, open it in the finder, and "take a good look around".

At this point, I'd begin "manually moving" things from the external drive to their appropriate places in the new account (on the iMac).

This is definitely more work, but it may get the job done when Migration Assistant couldn't...
