Is there a reason Percy is practically the only one at camp with a greek name? (Perseus)

think about it most of the time the mother または father didntknow they were with a god percys did

Well remember the myth of perseaus? In the myth his journey ended with a happy ending so his mom kind of wanted to give him that name so hopefully he would end with a happy ending too.

Remember his name is Percy because his mother could see the gods and monsters and she remembered that Perseus always triumphed so he was named after him
