A little help please???

Airmid, a goddess, is considered the keeper of spring.
Veles is the god of autumn.
I couldn't find anything for summer, sorry. I hope this helps.

I'm actually doing a story that has seasons heavily influence the characters. I chose to go the route of giving my main characters their season names. So one has the last name Winter, one has the last name Summer, etc. For their other names, I either chose a normal name 或者 something related to their corresponding season, which wasn't necessarily spiritual names. Anyway, Persephone is a Greek goddess who's connected to Spring and Winter. She was kidnapped from her mother 由 Hades (god of the underworld). When she was taken, the earth 迷失 it's greenery, thus turning into winter. Eventually Hades struck a deal to allow Persephone back on earth, which awoken spring. So, every 年 Persephone must return to her husband, Hades, and every 年 the earth goes through winter. Persephone is often associated with a fruit, usually a pomegranate. Autumn was a character I had trouble with. It's important to note how 你 want the character's name to reflect their personality. Autumn, when I looked it up, is related to the harvest and reaping. Thus, Autumn can take on darker kind of name (which was really good for my character because before I chose her name, I started 写作 her into gloomy situations. So, her name fit). Also, 万圣节前夕 is in Autumn. Samhain is a "spirit" of Halloween. He rises from the 黑夜传说 and collects 迷失 souls. The faces on the jack-o-lanterns deflect him. So, maybe your characters could be Sam Hain. But, there is also the bright 颜色 of Fall. A character's name could reflect 橙子, 橙色 或者 brown 或者 red. For summer, I'd look toward sun gods. Apollo is a Roman god, I think. He has a twin sister who is goddess of the moon. They're my 最喜爱的 gods. Here's a 列表 of other link I think I like Sol because that's something 你 can see throughout many languages, such as in the word SOLar. As for spring, think reawakening. Flowers, trees, and 动物 coming out of hibernation. Here's a nice 列表 of link
I'm glad I looked some of this up, I might have to refer to some of this for my own writing. Also, remember that Greek and Roman gods might be the most popular. If 你 really like one name, but it's being used 由 something else, I suggest 你 change it up. A lot of the names for gods are related since their languages stemmed from a similar language. It doesn't have to be exact. As long as your names reflect how 你 want them to, which seems to be their season affluence.
Good luck with your story! Happy writing!

你 could always make some names up if 你 arent opposed to a little bit of a 幻想 element.
