John Parker was born in 1830 in Crawford County, Illinois, the second oldest child of Silas Mercer Parker and Lucinda Duty. His younger siblings were Silas Mercer Jr., and Orlena. His older sister was Cynthia Ann Parker. This family and allied families, led by Silas' father John and brother Daniel, moved from Illinois to Texas in 1833. A large group under the family patriarch, Elder John Parker, settled near the headwaters of the Navasota River in present-day Limestone County. In 1834 they completed Fort Parker for their protection on the frontier. On May 19, 1836, a large force of Comanche and allied warriors attacked the fort, and in what became known as the Fort Parker Massacre killed five men and captured two women and three children: Parker, his sister Cynthia Ann, Rachel Plummer and her son James Pratt Plummer as well as Elizabeth Duty Kellogg.
Captivity
The Comanche's population had increased in large part by adopting captured women and children into the tribe, the former as child-bearing slaves and the latter as tribal members. The Comanche made little distinction from tribal members born into the tribe, and those adopted in. Children under puberty were tested for intelligence, strength and courage, and if they seemed acceptable in all, they were adopted into the tribe and taught to be warriors. Grown men captured alive were generally killed, while women over puberty could expect gang rape and slavery. Elizabeth Duty Kellogg was quickly ransomed from the relatively benign Delaware Indians by Sam Houston. Rachel Plummer endured nearly two years of captivity among the Comanche, and never saw her oldest child, James Pratt Plummer, again. Her second child, born six months after her kidnapping, was murdered by the Comanche, who claimed that the child interfered with her work. Parker was raised by the Comanche, as were his sister and younger cousin, John Pratt Plummer. The two boys were ransomed back in 1842. Plummer was returned to his grandfather and was able to readapt to white society, but Parker was unable to readapt and ran away from his family to return to the Comanches.
As did most young Comanche, Parker participated in many raids into Mexico during the September full moon, the "Comanche Moon," when the dreaded Comanche raids devastated Mexico all the way to Central America. On one of the raids, he contracted smallpox. The Comanche were returning from the raid with captives, horses, and other plunder, but they stopped briefly when Parker became too ill to ride, somewhere just north of the Rio Grande in West Texas. The Comanche were terrified that they, too, would catch this dreaded killer, which had killed over half the tribe during the epidemic years, and they left Parker to ride out the illness, leaving a girl they had captured on the raid to take care of him. Rather than leave to try to return to her family, the girl nursed Parker back to health. He then returned to Mexico with the girl and restored her to her home and family. He later married her.
Later life
Parker returned to the United States during the Civil War and served with Confederate troops in Texas. After the war, he returned to Mexico, where he died in 1915 on his ranch. He appeared to have been the only one of the Parker children who lived a happy life. The actorWilliam Smith played Parker in the 1969 episode "The Understanding" of the syndicated television series, Death Valley Days, hosted not long before his death by Robert Taylor. In the story line, Parker contracts the plague, is left for dead by his fellow Comanche warriors, and is rescued by his future wife, Yolanda, a Mexican.
