The best place to look is what’s currently in state top 10s that isn’t nationally, but exclude names that have been top 10 in the past and thus are on a downswing instead of an upswing.
For boys, that would be Lucas, Luke, Jack, Jackson, Jaxon, Jose, Henry, Owen, Samuel, Carter, Wyatt, Julian, Theodore, Dylan, Sebastian, Cameron, Grayson, Mateo, Asher, Levi, Lincoln, Easton, Ezra, Josiah, Hudson, Santiago, Ezekiel, and Kingston.
The most frequently used of these were Henry (18 states), Lucas (15 states), and Owen (14 states). That’s 3 more states with Henry than 2016, one more state with Lucas, and six fewer with Owen.
For girls, Victoria, Avery, Ella, Grace, Nora, Lillian, Aubrey, Addison, Aria, Paisley, Brooklyn, Lucy, Ellie, Sofia, Hazel, Eleanor, Camila, Mila, Scarlett, Maya, Luna, Genesis, Piper, Aurora, Kinsley, and Skylar. I would also add Elizabeth, since it’s liable to drift into the #9 or #10 slot at random.
The most frequently used of these were Elizabeth (13 states), and it’s otherwise all over, with the exception of Harper–I didn’t include it since it fell out the top 10 and it’s trendy, but it was still in the top 10s of 35 states, and it only had 100 fewer babies than the 10th-most-popular name. I foresee Harper and Abigail switching spots next year.
Of the other names there, I think Ella is most likely–it has the broadest demographic appeal, whereas a lot of the other names are really only popular in a handful of states. That’s why I don’t see Camila or Victoria making the top 10: Camila is overwhelmingly used by Hispanics, and Victoria is skewed Hispanic (the one state with Victoria in the top 10 is Texas), and I just don’t see there being enough Hispanics for those to get into the top 10.
If you’re curious, in 2016 21 states had Evelyn in their top 10, 26 had Oliver, and 31 had Amelia.
