Mr. Burford, my GGGrandfather, John W. Cox, M W, b. 1828, Georgia, married Almarinda Susan Johnson, 1847.
On the AR. 1860 Census, Pulaski Co., Bayou Meto, This Cox family was listed with only Wm. R., John P. Josephus and James living in the house hold. Calvin, Sara Virginia and White Everson died in AR.
