	It was not until 1919 that the widower Boone married again. He married Rachel Tharps that year after traveling to the United States for a furlough from Liberia, where he had been for nearly a decade. Like his first wife, Tharps was a graduate of Hartshorn Memorial College. In 1920, they returned to Monrovia, Liberia. They were there for the celebration of his Providence Baptist Church's one hundredth anniversary in 1922.
