SPARTANBURG, S.C. – Mary Louise Buck Hinckley, 89, of 400 Webber Road, and Southwest Harbor, died Saturday, Aug. 8, 2009. She was born Jan. 17, 1920, in Dallas, daughter of the late Francis Alexander and Harriet Knox Buck. She was the wife of the late George Lyman Hinckley. M’lou is best remembered for her wonderful sense of humor and her willingness to get involved in almost anything. She was an active volunteer in hospitals and libraries wherever she lived. She was up for any challenge – from running senior proms to sailing from Florida to Maine and back annually. She was a founding member of Southwest Harbor Fleet and served on the committee boat for many years. She was also a longtime member of Causeway Club, where she was frequently seen on the golf course or by the pool, running square dances or helping with the swim meets. Her home and her heart were always big enough to let more people in. Nieces, nephews and grandchildren were regular visitors, often for extended periods of time. She is survived by daughters, Penny Hinckley of Chestertown, Md., Midge Hinckley Smith of Spartanburg, S.C., Laurie Hinckley Towers of Naples, Fla., and Southwest Harbor, and Mary Anne Hinckley Mead of Vineyard Haven, Mass.; seven grandchildren and three great-grandchildren. She was predeceased by her brother, Frederic A. Buck. No service is planned at this time. In lieu of flowers, memorials may be made to Southwest Harbor Public Library, 338 Main St., Southwest Harbor, ME 04679 or to the charity of one’s choice. J. F. Floyd Mortuary, Spartanburg, S.C.
