William J. Mahanna II, 56, of Barneveld, New York passed away July 19, 2015 surrounded by his loving family. Bill was the first of 10 children and he taught us all many of life's lessons. He had a wonderful education at Oneida BOCES and he was a very talented athlete who won several medals in the Special Olympics. Bill loved life, music, dancing, swimming, bowling, skiing, biking, shopping and all of the family/friends gatherings. Bill had an infectious smile and when someone would give him a compliment, Bill would return the compliment right back. He took drum lessons for 20 years from various community musicians who Bill greatly admired. He received long-term services from The Arc, Oneida-Lewis Chapter and worked 29 years at the State Office Building; he loved all of his many friends and spoke of them even to this day. Bill had a very active life with all of his sisters, brothers and entire family that just adored him. Bill was our life and we were Bill's life. What we gave Bill, Bill gave back to all of us tenfold.
