If you want to use the name trick to evolve Eevee into a specific evolution in Pokémon Go, you can choose from the following names:

• Vaporeon: Rainer
• Flareon: Pyro
• Jolteon: Sparky
• Espeon: Sakura
• Umbreon: Tamao
• Glaceon: Rea
• Leafeon: Linnea
• Sylveon: Kira

Note that the name trick only works once per evolution, so if youve already used it for a particular evolution, it wont work again for that same evolution.
