Samuel Culbertson Orr was born near Jacksonville, Pennsylvania in 1875 to Franklin Orr and Martha Maclean Orr. After moving to Washington, Pennsylvania July of 1895, he attended Washington and Jefferson College, where he took classes in Greek, botany, English literature, and English constitutional history. Following his graduation, he entered the Western Theological Seminary at Allegheny, and in 1909, he moved to Buhl, Idaho, where he worked as an ordained Presbyterian minister at the local church. In the years to follow, he left his work at the church to purchase land and establish what would come to be known as “The Orrchard”—a fruit orchard growing apples, peaches, pears, and other produce. In March 1919 he married his wife, Margaret Peebles Orr, with whom he had three daughters: Joan Phoebe, Margaret “Peggy” Peebles, and Kathleen Maxwell. He handled management of the orchard throughout the Depression, until 1945 when he passed management over to his partners, Hubert and Claude Smith. After doing so, he continued to work and live on the farm with his wife. They took numerous trips east and to visit their children until May 1951, when Margaret passed away after a bout of viral pneumonia. Following her death, Orr lived out the remainder of his life in the house at The Orrchard alongside the Smiths, taking summers to visit his children and numerous grandchildren.
