Leslie William "Bill" Ross, born 9 September 1940 in Bend, Oregon, to Leslie Merl "Cotton" Ross and Neola Alice Reinhart, died from complications of diabetes and was buried in Bend, Oregon on 21 October 2005. Bill received his BS and MS in Mathematics. After working for many years in the aerospace industry first at NASA and later at Boeing, he retired to Central Oregon. He built a home on the Deschutes River and dedicated his time and skills to genealogy research. Bill was always generous in sharing his results and his considerable research expertise. Bill is survived by a brother and a sister, three nephews, and the four children of one of his nephews. Bill's mother and my mother were sisters. We will all miss him very much. Nora Besson
