On 18 August 1868, 3 brothers and one half-brother, sons of Thomas GRAY of Union County, arrived in the Arizona Territory, settling in the Salt River Valley in what later became Phoenix: 1) Josiah H. GRAY (1824-1892) b. GA 2) Columbus Harrison GRAY (1833-1905) b. FL, married Mary Adeline NORRIS (1846-1936) b. AR in Union County, 24 August 1865 3) Frank M. GRAY (1846-1894) 4) William Thomas GRAY (1/2 brother) (1852-1911) b. AR With them were two brothers from another family: 1) Thomas Gray GREENHAW (1845-1907) b. AR 2) Hosea George GREENHAW (abt 1849-?) b. AR Their mother and sister came with them, came later, or perhaps the whole family came in 1868. I have only found these two in the 1880 US census: Mother: Mary A. (Unknown) GREENHAW (abt 1817-?) b. AL Sister: Mary F. Greenhaw ORME (abt 1857-?) b. AR The fact that one of the GREENHAW brothers bore the name of the GRAY's father indicates that the families may have been friends for a long time; however, beyond a couple of marriages, I can find little about any GREENHAWs in Union County, or anywhere else. In 1878, Mary GRAY returned to Union County and brought her parents and her brother's family with her back to Arizona: Parents: James McKenzie (1809-1902) and Jane Rosella (1820-1907) NORRIS, both born in Georgia. Brother: Frank Coleman NORRIS married Sarah L. ROWLAND 1872 in Union County. Several of these folks were involved in the growth and development of Phoenix, Maricopa County, and the State of Arizona. Columbus ("Lum") was one of the first county commissioners of Maricopa County, and served in the territorial legislature. His half-brother William, and Mary F. GREENHAW's husband, Linley H. ORME, were both territorial county sheriffs. Hosea GREENHAW was instrumental in the formation of the Salt River Project, which irrigated the Valley. His brother was a JP and a ditch commissioner in an irrigation district in Buckeye, Arizona.
