Does he first turn up in Oklahoma/Indian Territory in 1891?

I'd never heard him called "Texas Newcomb" until today, and for some reason thought Slaughter's ranch, when Bittercreek worked for him, was in Oklahoma, but no it began in Palo Pinto, County Texas.

Born in 1837 in Sabine County, Texas, Christopher Columbus (C. C.) established frontier ranch in Palo Pinto County, Texas, in 1857 with his father, George Webb Slaughter, and his brothers. During the Civil War, C. C. served in the frontier militia and in the Texas Rangers. Afterwards, he drove cattle over Chisholm Trail and later moved operations to West Texas where, by 1905, he owned 40,000 cattle and controlled over one million acres.

C. C. Slaughter and Company, a cattle breeding venture, was established in 1873. Around 1877, C. C.'s ranch, the Long S, was one of the largest ranches in West Texas. His large holdings helped earn C. C. the title, "Cattle King of Texas

The first headquarters of Slaughter's ranch was established in 1898 near the site of present-day Lehman, but was moved a year later to a site two miles southwest of Morton. For all his interest in cattle breeding to produce crossings of Herefords and shorthorns of record size, Slaughter foresaw other economic developments for West Texas. In 1907 he predicted that "the fertile Plains...will become the breadbasket of the great Southwest."

So, it was 1898 before Slaughter established the ranch in Cochran County Texas. Which is next to New Mexico.

Terrorized by Outlaws.
GUTHRIE. I. T., Oct. 17.-Bill Dalton, the notorious bandit for whose apprehension a reward of $10,000 is offered, and two of his accomplices. Bill Dolin and Texas Newcomb, terrorized Stillwater. They paraded the streets with revolvers strapped to their belts and carried Winchesters in their hands. Many of the people of Stillwater recognized them
and reported the matter to officers, but the latter seemed reluctant to endeavor to catch them.

Thanks, y'all, any info appreciated.
