Ian ranks as name #72 in 2011 with SSA. The name Parker (one of our possible names) is #79. I've never met a Parker, and I've only known one other Ian while I was in school.
It's horrible when he tells someone his name, or if we order food and they try to "read" the name. He's gotten everything from "Eon," "eye-on", "Ivan," "Ann"... and then has to correct them.
