I believe I have found a link to Huntington's disease to the Peter's family in Westmoreland county, PA . Descendants of this family may include Hutchinson, Wohler, Irwin, Updergraff, Brickerstaff. A niece displayed early onset at 42 and is currently in hospice care at 52. Her father displayed Huntington's symptoms, although we never knew of "an official" diagnosis. Would be interested in hearing from family members possibly also affected. Some surviving members of one family currently considering testing in order to help family members from passing on the genetics to the disease.
