There are many reasons a particular baby name can spike in popularity. Sometimes it’s a resurgence of an old classic, or maybe a royal baby shepherds in a new era for Louis’ everywhere. In modern times, more often than not, a short-term blip in baby name popularity comes from a character in a popular movie or TV show. Thanks to Game of Thrones, we saw the rise of Daenerys (before, well, you know what happened). Frozen’s popularity led to a steep increase in Elsas; Ratatouille, a spike in Remys. So it’s not a surprise that two of this past year’s fastest-rising baby names owe their time to the wild popularity of Yellowstone. What is a surprise is which names from the beloved drama are trending.
