How to create a clone of an object with a different name

Hi guys, Im making a list of my gameobjects and im trying to add a number identifier to the end of each new objects name. So the first object created would be "Enemy" the 2nd object would be "Enemy1", third would be "Enemy2" etc. I have provided the code i have so far below. The Enemy Object is what is being cloned. and where I have enemyList.add(Enemy) I want to make it something like enemyList.add(Enemy + intToString(enemySpawned)) or something. Thanks guys,

 public class EnemySpawn : MonoBehaviour {
 
     public GameObject Enemy; //creates the enemy game object
     // Use this for initialization
 
     public int enemyCountSpawned = 0;
 
     public static List<GameObject> enemyList = new List<GameObject>();
 
     void Start () {
 
     //    enemyList.Add(GameObject.Find ("Enemy")); //this adds the initial enemy to the list
 
         StartCoroutine (EnemySpawner());
     
     }
     IEnumerator EnemySpawner(){
 
         while (enemyCountSpawned<3) {
 
                         int randomNumber = Random.Range (0, 4);
 //                        print ("the random number for unit spawning is" + randomNumber);
         
                         switch (randomNumber) {
                         case 0:
                                 Instantiate (Enemy, GameObject.Find ("SpawnPointLeft").transform.position, Quaternion.identity);
                                 break;
                         case 1:
                                 Instantiate (Enemy, GameObject.Find ("SpawnPointRight").transform.position, Quaternion.identity);
                                 break;
                         case 2:
                                 Instantiate (Enemy, GameObject.Find ("SpawnPointTop").transform.position, Quaternion.identity);
                                 break;
                         case 3:
                                 Instantiate (Enemy, GameObject.Find ("SpawnPointDown").transform.position, Quaternion.identity);
                                 break;
                         }
             enemyList.Add(Enemy);//adds the enemy to the list
 
             yield return new WaitForSeconds(5f);
             enemyCountSpawned++;
 
         }
 
     }
     // Update is called once per frame
     void Update () {
     
     }
 }
