Diego
One would have to assume that it could be Marquez, the same as Dora's last name. But since we don't know who's side of the family he is from we will never really know unless the author adds some information.
His name is Diego. Yes, he is the cousin of Dora. In one of the episodes Dora says "We'll be going on an adventure with my cousin, Diego."
If Diego is the son of Dora's aunt or uncle, then they are first cousins. If Diego is the grandson of Dora's great aunt or great uncle, then they are second cousins.
Diego & Dora are cousins and are both Spanish.
