from the Portales Valley News, Thursday, December 31, 1931:
With the passing of Rev. O. W. Carter at his home in Portales Christmas Eve at 8:45 o'clock. One of the pioneer preachers of the Southwest was called to his reward.
Rev. Carter was born in Crawford county, Missouri on Jan 5, 1834. After graduation from the Stephensville academy in Missouri, Mr. Carter was ordained a minister of the gospel and was sent to St. Louis to do missionary work for the Cumberland Presbyterian organization and for more than eighty following years he has been a missionary preacher.
After serving his native state of Missouri for several years, he felt the call to go to a more remote field and after the close of the war of the sixties he went to Texas, and was the missionary preacher in the southern part of that state. It was here that he met and married his wife who was an earnest Christian and has worked side by side with her husband in their labor of saving souls. Mrs. Carter, now at the advanced age of almost 92 years, is bearing bravely the passing of her husband, a companion of almost sixty years.
In 1902 Rev. and Mrs. Carter came to New Mexico and were known to all the people of this eastern section for their faithful Christian work and kindly assistance. They made their trips to the scattered churches and settlements on horseback to give to the people the message of God's love for the world.
On the nineteenth of last October Rev. Carter fell and broke his limb at the hip joint and from this he never recovered and grew gradually weaker until he slipped peacefully to sleep just at that season when the world was remembering the birth of the Christ, of which he has preached for four score years.
The pastor of the Methodist church, Rev. R. F. Davis, has been a frequent visitor with Rev. Carter during his last days of illness and was in charge of the ceremonies, which were held last Saturday morning. The Masonic lodge conducted burial rites at the Portales cemetery, for Rev. Carter had united with the Masonic bodies when a young man.
Of the five children born to Rev. and Mrs. Carter, all were present with their parents during the present year, when a family reunion was held here, but only the son and the daughter from Texas and the daughter in Portales were present at the funeral service Saturday morning.
The children are Mrs. K. T. Kelly of Earth, Tex.; W. W. Carter from Dodsonville, Tes; Mrs. C. H. Wolfe, Hollis, Okla; Mrs. C. M. Sloan, Strong City, Okla; and Mrs. F. D. Galloway of Portales.
The six friends carrying the body of this esteemed and honored pioneer to its last resting place were fellow Masons, and included Floyd Kennedy, Marion Stinnett, C. V. Harris, J. A. Fairly, Ed Copeland, and John W. Ballow.
Attendants from the Wheeler Johnson Mortuary were in charge of the burial services.
