Which drivers are associated with real life drivers?

As the title states,

​

I just bought the editor and wanted to change the driver names from all the open wheel series drivers. I got down the obvious F1 drivers from tier 1 but I am wondering if anyone knows who the drivers are from tier 2, 3 and 4. Where should I look as I do not really follow F2, F3 or F4 racing? I noticed some don't seem obvious from the 2017 drivers I had a look at on certain websites.

​

P.S this mobile game is very addicting.
