GetComponentInChildren by name

I have an object

public GameObject object;

What I need is to find it in a gameobject.

The way my prefab looks like

Parent

Child(one)

Child(two)

What I need is to find the child with the name two and set it as "object".

Preferred in c#, but js is fine too.

Thanks

EDIT: After re-reading the question, I'm less certain as to what you want to do. So here's a few JS example:

//find a Transform children in current GameObject
aTransform = transform.Find("LeftShoulder/Arm/Hand/Finger");

//access an object in a component script
aVariable = GetComponent(theScript).aValue;
