The way stock photo sites work is that usually the photographer hires a model local to them to do photo shoots, this means it's mainly models that are unknown and they're always uncredited on the stock sites. Therefore finding the identity of models from those sites are pretty much a dead end, unfortunately.

Best I could do was find the name of the photographer, Nick Vango or Nickvango : https://stock.adobe.com/contributor/200652993/nickvango
