Sarô was a storyboarder for 3 episodes in season 1: "Francine's Bad Hair Day", "Arthur Accused!", and "My Dad, the Garbage Man"
Later, in season 7, there was a storyboard artist named Jean Saro for 2 episodes: "Jenna's Bedtime Blues" and "Buster's Amish Mismatch"
Are these the same person?
I personally think not because in the latter's case there is no accent mark over the 'o'.
