using System;
using System.Linq;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Linq;
public class MainClass {
    public static void Main() {
        XDocument xDocument = new XDocument(new XElement("Books",
  new XElement("Book",
    new XAttribute("type", "Author"),
    new XElement("FirstName", "J"),
   new XElement("LastName", "R")),
  new XElement("Book",
   new XAttribute("type", "Author"),
   new XElement("FirstName", "E"),
   new XElement("LastName", "B"))));

        foreach (XElement element in
         xDocument.Element("Books").Descendants("FirstName").Ancestors()) {
            Console.WriteLine("Ancestor element: {0}", element.Name);
        }
    }

Without Calling the Ancestors Operator

using System;

using System.Xml;
using System.Xml.Linq;
public class MainClass {
    public static void Main() {
        XDocument xDocument = new XDocument(
         new XElement("Books",
           new XElement("Book",
            new XAttribute("type", "Author"),
            new XElement("FirstName", "J"),
           new XElement("LastName", "R")),
           new XElement("Book",
            new XAttribute("type", "Author"),
           new XElement("FirstName", "E"),
           new XElement("LastName", "B"))));

        IEnumerable<XElement> elements =
         xDocument.Element("Books").Descendants("FirstName");

        foreach (XElement element in elements) {
            Console.WriteLine("Source element: {0} : value = {1}",element.Name, element.Value);
        }

        foreach (XElement element in elements) {
            foreach (XElement e in element.Ancestors())
                Console.WriteLine("Ancestor element: {0}", e.Name);
        }
    }
