Order childish and retrieve another child value

Question

I have the following dataset:

person-base 
{
     -K771quXhYWTo-F8oei9 
     {
        person: "Sam"
        value: 2
     }
     -K771uFngeQ6j0rvDhN_
    {
        person: "Joe"
        value: 1
    }
}

I am trying to get the value of one of these keys based on this person. I created a query that I use to indicate the value of a person that matches the value of my variable personName (in this case, “Sam”), and still, based on what I see in the console, it correctly extracts the corresponding key and this children.

My code is:

var personRef = new Firebase("https://person-base.firebaseio.com/");
var personName = "Sam";

var query = personRef.orderByChild('person').equalTo(personName);
query.on('value', function(snapshot) {
    console.log(snapshot.val());
    console.log(snapshot.val().key()); // error 
});

My plan was to get the parent key (generated using .push) that contains the value of my face, and then run something like the code that I have below to get the value

personRef.child(key).on('value', function(childSnapshot) { 
   var obj = childSnapshot.val();
   console.log(obj.value);
});

However, I cannot get the parent with my request.

query.on('value', function(snapshot) {
    snapshot.forEach(function(sam) {
      console.log(sam.val());
      console.log(sam.key());
