NUTRIOSO, ARIZONA--- JOHN WESLEY ADAIR DEAD Pioneer and Veteran of the "Mormon" Battalion. Special Correspondense. Nutrioso, Apache Co., Arizona, May 20,--On May 5th, 1903 John Wesley Adair, died at his home here. He was born Feb. 18, 1820, in Pickens County, Alabama. He became a member of the Church of Jesus Christ of Latter-day Saints about 1842. Gathered with the Saints at Nauvoo and acted as one of the minute men, being driven out from that city with the Saints.
In 1846 Elder Adair joined the celebrated "Mormon" batallion, at his country's call, to fight against Mexico; marched from council Bluffs to California on foot, and suffered the terrible hardships incidents to that notable journey; joined the Saints in Utah in 1848 and moved to Arizona in 1880. His life has been spent on the frontier; has been a very hard-working man; always full of faith in the Gospel, and died at the age of 83. He was the last one of a large family to depart this life.
John was a Pvt. in Co. "C" Mormon Battalion (enlisted 18 Jul 1846 at Council Bluffs, IA.; honorably discharged 16 Jul 1847 Los Angeles, CA). Also, known as George Wesley Adair or Wesley Adair. Was a member of Maj. John Wesley Powell's 1871 expedition of the Colorado River canyon with Jacob Hamblin.
George Adair apparently first became associated with the Powell expedition when he helped Jacob Hamblin take in supplies to the mouth of the Paria late in October, 1871. On February 22, 1872, he was put on the payroll at $40 per month, and was associated with the party through 1872-73 as horse wrangler, packer, and man-of-all-work.
Wesley Adair was a private in the Mormon Battalion, Company C, and as of March 1882 was a farmer in Arizona. He made it to California and was part of the Hancock-Los Angeles company of about 150 men who travelled up California's Central Valley to Sutter's Fort. Many went on to Salt Lake City immediately, but Wesley was one of the 105 who remained behind and worked for Sutter. The group of 39 veterans and some others arrived between 24 Sep. and 6 Oct. 1848 in Salt Lake. Wesley was one of thirty soldiers who later settled Arizona and contributed greatly to the colonization of Arizona. His nephew Benjamin Richey was also a private in the same company.
