"Wilbur, third son of Milton and Susan Wright, was born April 16, 1867, at Millville, Indiana. Two years later the family moved to Dayton, Ohio, taking a small dwelling on Hawthorne Street which was to be its home for more than four decades. In that house, Orville came into the world August 19, 1871, and on his third birthday, Katharine was born. In the same home, Susan, the mother, died when Wilbur was 22 and Orville was 18."
