Barbara, I found the same census Hugh did, searching for Henry Constant's name, in KY.1870. Found the "John Constant"b.1832 on 1850 Hart Co.KY census.
Thomas Constant 46,b.NC, farmer Susan 42,b.KY **John 18,b.1832,KY,farming William 16,b.KY, farming Henry H. 9,KY Mary 2,KY. Also listed in this census is a man named Henry Orlander 50, b.VA. He is listed with the family on the 1860 census also. Another female listed with family on 1850 census was Martha Hammon 14,b.KY. If you are from Texas, then you know Kaufman and Van Zandt Co's are neighboring counties. alice
