Henry was born to Marcus Lafayette Green & Permelia Carter Green in Van Buren County, Arkansas. His childhood was spent during the Civil War and by 1869 he had a step-mother, Nancy Johnson Green, and was on a wagon train with his family. traveling to Oregon. A trip which he remembered as his walking most of the way to the Williamette valley. There they first settled in Silverton.

About 1876 he took a trip to the Walla Walla area of Washington looking for possible homestead sites in either Oregon or Washington. His traveling companions decided return to western Oregon but Henry stayed longer to help the George Sanders family, who lived 18 miles north of Fort Walla Walla, with preparing for the winter and bringing in the harvest.

In July of that year, there was an indian uprising and Mr. Sanders loaded up his family to take shelter at the Fort but his elderly parents couldn't travel. so Henry volunteered to stay with them. He and the elder Mr. Sanders excavated a cave in a nearby riverbank disguised the entrance, and the three of them camped out there for 10 days until the danger was over. This resulted in considerable good will among they locals when they heard of his valor. (Source:Smith and Shaw,"In the Land of Bunch Grass, Gold and Trees," a private publication.)

A year or so later, Henry homesteaded in the Milton-Freewater area of Oregon and began ranching. November 10, 1889 he became the legal guardian of his sister Mary's children, Rosa and William Johnson (it is thought Mary passed away that year).

In July 1896 Henry had a run-in with another rancher, Joe Caseday. They had a few harsh words, bullets flew and Henry's horse ended up the worse for wear. Years later, Joe Caseday became a deputy Sheriff and a good friend of Henry's brothers, Arthur and Albert.

A few more years passed and Henry met Alice R. Graham Frazier, a divorced lady. They married on July 4, 1900 in Walla Walla: Alice had four children at the time. Together, they continued ranching in Milton until Henry's death in 1936.
