Elizabeth's husband, Elmer Weston Littlefield II, was a descendant of Mary Littlefield's son, Ithamar Littlefield. I think you contacted me in 2007 when you were doing a class project, and I did not know their Littlefield lineage at that time, but have figured it out, using the LDS records. If you want a report of the ancestors, send me an email at KenAkers@ij.net.
Thanks,
