from experience i find for guys it's names like: steven/stephen, daniel, tony, michael and for girls it's mostly like: jenny, michelle, mary, & fruit names lol (cherry, mango? lol)
guys: Roger, Aaron, Kenny, Steven, Jason, girls: Lily, Michelle, Tiffany, Jennifer, Kelly, Amy, June, ok, these are my classmates names, and yes, they are East-Asians. seriously, there are too many Michelles in my grade
Mines Cindy ^^ Borrring name!! Boys - Henry, Oliver, Raymond, Jason, Kevin Girls - Tracey, Linsey, Amy, Lucy
I think for both, it's just the "ie" or the "y" sound that makes the names common, if that makes sense.
