Starting in 1875 and covering a span of almost 100 years, three missionary families exhibited bravery, endurance, and sacrifice when their very lives were at risk. William David Powell and his wife, Mary Florence Mayberry Powell, were missionaries to "Wild West" Texas then Mexico. In the period 1910-1947 (including during Japanese occupation) their daughter Florence and her husband, Hendon M. Harris, were missionaries to Kaifeng, China. Their son Hendon M. Harris Jr. and his wife Marjorie Weaver Harris served as missionaries to Taiwan and Hong Kong. Referencing 55 books and 39 articles, this biography gives numerous firsthand accounts from all three families.
