Religious baby names aren't unusual across any faith; however, when devout Catholics choose to reflect their faith in their child's name, they often go the way of a saint, like Mary, or the way of a virtue, like Grace. You'd be hard-pressed to find a baby named Lent. Not the case with Ramadan, as the religious observance has also become a common name for Muslim baby boys. While the name was a more popular choice in the '90s than it is now, Ramadan could be making a comeback. According to the website BabyCenter, the name's popularity has been steadily climbing since 2005.
