I will email you more detail, but just as I was about to give up, I found something on grandfather:
William Henry S. Alderferb 1852 d 1926 married Eliza Jane Sissel (or Thissel) b 1854 d 1942 Wm. Henry Alderfer was born in Mahoning Co., Ohio; and was the son of Isiah B. Alderfer and Amelia Sanders.He is buried in Marshall Co., Ind. Children are listed as Anna, Clinton, Ona, and Clarence. (This information from the Alderfer Family in America, p.258)
Perhaps you could fill us in on the Clarence family information as you find out more.The Alderfer book only has information on Clinton and his children.
