My brother John has turned up a small collection of pictures of our grandfather in the online collection of the Library of Congress.
Our father's father, Charles Delahunt Mahaffie Sr., was a member of the Interstate Commerce Commission (ICC) from 1930 to 1955 (he was appointed by President Hoover). At some point during that time, I believe, he sat for this portrait. I think he would have been in his late forties or in his fifties here.
He's very dignified in this photo, and in all others that I've seen. Perhaps there's hope for me?
Of course, my grandfather was a really remarkable man. He was born in 1884 in Olathe Kansas, but moved to Oklahoma as a homesteader as a boy. He graduated from Kingfisher College in 1905 and went to Oxford as a Rhodes Scholar. After practicing law for a few years, he came to Washington DC and worked for several agencies before becoming an ICC commissioner.
He also married Isabel Ruth Cooper and fathered my Dad, for which I am most grateful.
