In February 1866, Jocelyn married Mary Chamberlin Edgell.[2] They were the parents of three children ― Louise, Dorothy, and Stephen Jr.[2] Louise was the wife of Julian B. Clark, a wealthy Burlington, Vermont heir disabled by polio, whose hobbies included hunting and farming.[2][5] Dorothy was the wife of William I. Westervelt, a career army officer who attained the rank of brigadier general.[2][6] Stephen was a 1916 Harvard College graduate and World War I veteran.[2] He later resided in France and authored a 1953 biography of his father, Mostly Alkali.[7]
Peter Westervelt (1919–2015), the son of William I. Westervelt and Dorothy Jocelyn, was a prominent college professor and research scientist.[8][9]
After his discharge from the wartime volunteers, Jocelyn was commissioned as a second lieutenant in the regular army's 6th Infantry Regiment.[1][3] He continued to perform post-war occupation duty during the Reconstruction era, this time in South Carolina.[3] He was promoted to first lieutenant in July 1866, and beginning in 1867 served with the 6th Infantry at Fort Gibson, Indian Territory.[1][3] As part of post-war force reductions, Jocelyn was mustered out of the 6th Infantry on 1 January 1871.[1] On 9 March, he returned to duty, this time as a second lieutenant with the 21st Infantry Regiment.[1]
During 1871, Jocelyn served in Arizona Territory, where he took part in the Yavapai War.[3] From 1872 to 1874, he was posted to northern California and southern Oregon, and was stationed at Fort Bidwell, Camp Warner, Fort Klamath.[3] Jocelyn was promoted to first lieutenant on 4 April 1873 and captain on 19 May 1874.[1] In 1875, population increases that followed the development of gold mining that resulted from the 1867 Alaska Purchase led to the U.S. takeover of Fort Stikine, a former British trading post on the panhandle.[3] The post was christened Fort Wrangel, and Jocelyn commanded the post and the 21st Infantry's Company G until 1877.[3][10] He participated in the 1877 Nez Perce War and commanded Company B, 21st Infantry during the Battle of the Clearwater and Battle of Camas Creek.[3][11] He also took part in the 1878 Bannock War, after which he was granted a year-long leave of absence during which he traveled extensively in Europe.[3]
During his time in Washington Territory, Jocelyn earned a reputation as an expert in military drill and ceremony, and units under his command won several competitions during the 1880s and 1890s.[3] Beginning in 1884, the 21st Infantry garrisoned a succession of posts in Wyoming, Utah, and Nebraska, and Jocelyn served successively at Fort Fred Steele, Wyoming, Fort Duchesne, Utah, Fort Douglas, Utah, and Fort Sidney, Nebraska.[3] In February 1890, he received promotion to the brevet rank of major to recognize his gallantry during the Nez Perce War.[2]
In June 1897, Jocelyn was promoted to major in the 19th Infantry.[1] During the Spanish–American War he was assigned to Fort Ethan Allen, Vermont, where he served beginning in May 1898 as mustering-in officer for the 1st Vermont Infantry Regiment, a unit of United States Volunteers raised for the war.[12] He served as mustering-out officer for the same unit in August 1898, and he was promoted to lieutenant colonel of the 25th Infantry in March 1899.[1][12]

Between 1899 and 1901, Jocelyn served in the Philippines with the 25th Infantry during the Philippine–American War.[4] He was promoted to colonel and commander of the 14th Infantry Regiment in February 1901.[4] Jocelyn commanded U.S. forces on the island of Samar in 1903, and the Department of Visayas in 1904.[4] In 1904, Jocelyn performed temporary duty as professor of military science at the University of Vermont.[13] From 1904 to 1906, Jocelyn served as chief of staff of the army's Pacific Division, and in this assignment he aided in coordinating the US government's response to the 1906 San Francisco earthquake.[4][14] He was promoted to brigadier general in June 1906 and from 1906 to 1907, Jocelyn commanded the Department of the Columbia.[1][4] Having reached the mandatory retirement age of 64, he retired as a brigadier general on 1 March 1907.[1]
In retirement, Jocelyn resided in Burlington, Vermont, where his interests included membership in the Military Order of the Loyal Legion of the United States.[1] He became a member in California in 1884.[1] In 1894, he transferred his membership to the Vermont commandery.[1] After retiring from the army, Jocelyn served as a member of the Vermont commandery's executive council from 1908 to 1909.[1] He was senior vice commander from 1910 to 1911, and commander from 1911 to 1912.[1]
