Butler Washington died in infancy, but a precise date and medical cause have not been established. He was the first child of Augustine Washington and Jane Butler, born in 1716, and an elder half-brother of George Washington. The family chronology and the National Park Service's history of Washington's birthplace identify the infant separately from Lawrence, Augustine Jr., and Jane, the other children of the first marriage. The short lifespan records a family loss before George's birth in his father's later marriage to Mary Ball. It does not establish a particular childhood infection, congenital disorder, or accident. No reliable sequence of symptoms, treatment, final care, or burial-day events has been recovered in the supplied material. The death is therefore retained as an infant bereavement without turning a birth year into a definite death year or inventing the circumstances of the child's last hours.
