Getting 2 Camera Components inside Script by Name

I have this code:

private Camera cameraObj; 
private Camera thirdPersonCamObj;

void Start ()
{			
cameraObj = GetComponentInChildren<Camera>();
thirdPersonCamObj = // TODO: I want to point it to another Camera.
}

So I want to point each Camera object to a different Camera component inside of Unity, but I need to do it using the Camera’s name inside Unity. How do I do this?

A camera is always part of a game object, thus it can be found by name with GameObject.Find, like this:

private Camera cameraObj; 
private Camera thirdPersonCamObj;

void Start ()
{      
  cameraObj = GetComponentInChildren();
  // find the camera "Camera Two":
  thirdPersonCamObj = GameObject.Find("Camera Two").camera; 
}
