The early life of Benjamin is unknown. Benjamin married Elizabeth Christiana Ashment on Aug 9, 1869 in Salt Lake City, Utah. They lived in Salt Lake until 1870 when they were asked by the Church of Jesus Christ of Latter-day Saints to help colonize Soda Spring, Idaho. When they reached Richmond to visit the Ashment family and rest during their journey, their outfit was stolen, and the Peart family decided to remain in Richmond.
The Pearts lived in Richmond until 1872, then Franklin, Idaho until 1877, moving back to Richmond.Â
