In order for a rare baby name to make the cut and appear in the SSA’s baby name data for the first time, it has to be given to at least 5 babies (of either one gender or the other) within a given year.
The other names that debuted with ten-or-more baby boys in 2017 were Amunra, Arjunreddy, Irtaza, Ledgen, Gurbaaz, Caspen, Meliodas, Sreyan, Tewodros, and Yeziel.
Debuts lower down on the list include: Aarushreddy, Imronbek, Benjen, Kadafi, Killiam, Agambir, Almighty, Bamlak, Kuiper, Munther, Owsley, Slayer, Tolkien, Tuguldur, Vandawt, Zage, Zealous, Aoto, Bender, Bodhisattva, Cerulean, Go.

Update, May 2019: The top names of 2018 just came out. The SSA noted in its press release that name Yara rose from 986th place (2017) to 672nd (2018). Also, the name Khal finally debuted — seven years behind Khaleesi. So did Rhaegar, Aegon, and Myrcella.
Update, September 2020: The top names of 2019 came out late this year (due to Covid), but in this set I noticed three more GoT-inspired entries: Rhaella, Margaery, and Dracarys — the third of which isn’t even a character name, it’s a word that means “dragonfire” in High Valyrian. Daenerys uses the word dracarys to order her dragon to breathe fire.
Update, May 2020: The debut names of 2020 include Tormund, inspired by Tormund Giantsbane.
