Although it may be of no particular interest to anyone, I can add this: Nevada Jetmore and Mr. Marburg had one daughter, Wilhelmine, as noted on this forum. The daughter married Hulbert Yerkes. From that union one child was born - Albrecht Marburg Yerkes. He, in turn, married Martha Stewart of Topeka, and moved to the Los Angeles area about 1940. They, in turn, had two children, Robert Stewart Yerkes and William Marburg Yerkes. Marburg died in 1963. Robert and Willam remain alive. I met Wilhelmine only once, in Topeka, in the 1950's.
