Quanterrious is an uncommon, unique first name of African American origin. It's derived from Latin roots, 'quantus' meaning how much or how great, and 'arius', relating to a person engaged in, or devoted to. Thus, it translates to 'devoted to quantity' or 'greatness'. This name was popularized in the United States during the late 20th century.
"Quaterrious saw its peak popularity in the late nineties and early 2000s with five births recorded each year."
