He suffered from tuberculosis as a child. The disease eventually necessitated the amputation of the lower portion of his left leg.
He was married to Hannah Johnson Boyle, with whom he had a daughter.
He was a friend of author Robert Louis Stevenson. Stevenson, in fact, based his "Long John Silver" character upon Henley.
His daughter, Margaret, died at the age of five and became the inspiration for the character of Wendy in J.M. Barrie's classic children's novel Peter Pan.
