William Randolph McCreight is a physicist and mathematician with experience at NASA in orbital analysis, and at Boeing Aerospace Division predicting the effects on spacecraft from atomic explosions in space. In 1965 he was assigned to England and subsequently lived and worked in England, Sweden, Belgium, Switzerland, Germany and South Africa. He lived in the Far East three years and has professional experience in every western European country, some eastern European countries and Turkey. He became interested in genealogy when examining papers in his great-great-grandmother's trunk. This interest intensified with his first personal computer in 1975 and the advent of genealogy computer programs. He now has over 17,000 names, all confirmed by documentary and historical sources. He is now retired in the Taunus Mountains in Germany and spends his time primarily taking history courses with emphasis on Europe in the Bronze Age to the middle ages, and genealogy research.
