David Rogers Killian and Bradley Allen Roberts match 36 of the 37 markers tested. Mr. Killian took the Y-DNA test to trace his ancestral roots. His earliest confirmed ancestor is James M. Killian born 6 Feb 1877 in Illinois. His birth date is from WW I Draft Registration. He was married twice. First to Pearl Myane on 21 Jul 1902. She was born in Yazoo Co., MS. The first time I find James is on the 1910 census: Justice Precinct 2, Orange, Texas. James was a blacksmith in the lumber industry and railroad shops around Texarkana. His children were born in Louisiana, Texas and Arkansas.
I hope this helps,
