The farmhouse is no longer there, but I know where the property was located and I have plotted the location using Google-Earth. If interested I can send you a copy. Cyrus G. Cook died Sept. 11, 1911, in Tyrone twp., Blair Co., Pa., he is buried at Old Menallen/Friends Grove in what is today Butler twp., Adams Co.
