OAR was a favorite book of both my wife and I. We decided that if our first child was a boy, he would be named Quenton, and if a girl, she would be named Cassidy. Quenton joined our family a decade ago. Followed a few years later by Parker.
The spelling of Quenton in the book is a non-traditional way, as Quentin and Quinton are more common. Thus, everyone seems to misspell my son's name, not that it is a huge issue for him. He actually really likes the name, and I think he feels that it is unique compared to the other kid in his class, especially when combined with his last name.
Both kids know where the inspiration for their names came from, though they have not read the book yet. Perhaps when they are older. While it would be great if they grew up to enjoy running, we make sure they know that the main thing is to just pursue an active lifestyle.
