Do you check the box "Send me an alert when anyone replies to this thread"? In Oct 2011 you posted in Cass County seeking the same info. I forwarded census records locations for 1850 Independence, AR, 1860 Independence, AR, and 1870 Phelps, MO. Add to those, 1880 AR-Miller-Sulphur-198-Image 15. Per https://familysearch.org/ G. W. Walker wed Mire Misshe Brown, 19 Aug 1875 in Miller, AR. She was the mother of Noah Andrew and James William. I do not find a son, Avery? When/where was he born? Online death certificates: James William Walker (20 Aug 1880? - 13 Apr 1954), G. C. Walker (23 May 1887 - 25 Jul 1939), and Vernon Timothy Walker (27 Dec 1894 - 22 Nov 1957). Guessing Noah died Oklahoma?
