My work with linked lists works, but it does not display the whole list

Working with my linked lists works, but it does not display the whole list

here is my code When a user enters a name and contribution, he saves it in a list. When I print the list, only the last name entered by the user is displayed. I think its in my AddToList function is a problem Thanks

#include <string>

using namespace std;

struct PersonRec
{
    char aName[20];
    //string aName;
    int aBribe;
    PersonRec* link;
};


class PersonList
{

private:
    PersonRec *head;
    bool IsEmpty();


public:
    PersonList();
    ~PersonList();
    void AddToList();
    void ViewList();

};

#include <iostream>
#include <string>

using namespace std;

#include "personlist.h"

PersonList::PersonList()
{
    head = NULL;
}

PersonList::~PersonList()
{
    PersonRec *current, *temp;
    current = head;
    temp = head;
    while(current != NULL)
    {
        current = current->link;
        delete temp;
        temp = current;
    }
}


bool PersonList::IsEmpty()
{
    //PersonRec *p;

    if(head == NULL)//it has no nodes head will poin to NULL
    {
        return true;
    }

    else
    {
        //p = head;
        return false;
    }
}


void PersonList::AddToList()
{
    PersonRec *p;


    head = new PersonRec();   

    //if(head == NULL)
    //{
    if(!IsEmpty())
    {
        //head = new PersonRec();

        cout<<"Enter the person name: ";
        cin.getline(head->aName, 20);
        //cin>>head->aName;
        cout<<"Enter the person contribution: ";
        cin>>head->aBribe;
        //head->link = NULL;
        //}
    }    

    else
    {
        p = head;
        while(p->link != NULL)
            p = p->link;
        p->link = new PersonRec();
    }


}//end function

void PersonList::ViewList()
{
    PersonRec *p;
    p = head;

    if(IsEmpty())
    {
        cout<<"List is Empty "<<endl;
    }

    while(p != NULL)
    {
        cout<<p->aName<<" "<<"$"<<p->aBribe<<endl;
        p = p->link;
    }

}

#include <iostream>

    cin.ignore();
