There's a Shinto Uchiha on the Naruto Fanon wiki. That character is purely fan-made and not an actual canon character.
The only real character that comes close to the name is Shino, but everyone forgets about him. xD
Shinto is a spiritual belief that's popular in Japan, along with Buddhism, and both are frequently referenced in Naruto series.
One of these answers must be the one you're looking for. xDD
