Making an array of specific children inside Hierarchy

So I have a set of objects inside a group like this :

The Ref_Floor is a prefab that exists several times and I would like to make an array that contains all the Ref_Laying and another one that contains all the Ref_Standing (they are always inside the parent REFERENCES)

So right now I'm doing this to get an array with all the Ref_Floor:

 var actorFloorTriggerParent : Transform;   //This is the REFERENCES transform
 var actorFloorTriggerArray : Transform [];
 
 //On Awake ()
 
 actorFloorTriggerArray = new Transform [actorFloorTriggerParent.childCount];
     
     for (var i=0; i < actorFloorTriggerParent.childCount; i++){
         actorFloorTriggerArray[i] = actorFloorTriggerParent.GetChild(i);
     }

But now I'm not sure how I can get the arrays for the Ref_Laying and Ref_Standing. This is what I was trying so far. My idea was to look for the children by name and add them but the code isn't really working:

     actorFloorStandArray = new Transform [actorFloorTriggerParent.childCount];
     actorFloorLayArray = new Transform [actorFloorTriggerParent.childCount];
 
      for (var child : Transform in actorFloorTriggerParent){
       if (child.name == "Ref_Laying"){
               for (var c=0; c < actorFloorTriggerParent.childCount; c++){
                     actorFloorLayArray[c] = child;
                 }
       }
       }

Any help very appreciated!
