You can use a neat name generator to avoid cracking your brains over authentic names for your personas.
First, click on the GENERATE NAME button.
You'll see a nice popup where you can choose the country of your persona as well as her sex.
Make your choice or leave it as random. Click on the refresh icon and you'll get a nice authentic name based on the parameters you've set!
