I know little about Nancy Ann Childress (sometimes Childers) beyond the barest genealogical facts:
She was born 10 September 1848 in Clark County, Missouri, the daughter of John Milton Childress and Nancy Conyers.
She married three times, first to James Osburn on 11 February 1868 in Lewis County, Missouri; he disappears from her life within a couple of years, and I don’t know what happened to him. Nancy married again to George W. Armour, on 12 November 1871, in Lewis County. She raised seven children with him before he died on 12 September 1890, still in Lewis County. And third, she married James T. Turner on 21 December 1897, in Lewis County. Nancy outlived this third husband by many years – he died in 1907, and she lived until 1924, when she died in Illinois.
