There's a town by the name of Gilroy in California. It's known for the garlic grown in the surrounding areas.

...And trust me, you do NOT want your child's name associated with the city of Gilroy. Awful place.

This name reminds me of Gilderoy Lockhart - A "narcissistic wizarding celebrity who has written many books on his fabulous adventures encountering dark creatures" from Harry Potter (http://en.wikipedia.org/wiki/Gilderoy_Lockhart#Gilderoy_Lockhart), who is in actuality a fraud and a coward - Not an association I would want to have with my child's name!
