From “Hardesty’s History of Lincoln County, West Virginia,” published by H.H. Hardesty, we find this entry for Isham Roberts, who resided at Hart in Lincoln County, West Virginia:

Son of Isham and Dicie (Roberts) Collins, was born in Martin county, Kentucky, in 1861, and settled in Lincoln county in 1877. His mother resides in this county, but his father is in Minnesota. Isham Roberts was united in the holy bonds of matrimony, in Lincoln county in 1883, with Martha J. Brumfield. She was born in 1865, and her parents, Paris and Annie (Toney) Brumfield, are natives of this county. Mr. Roberts is a prosperous young merchant in Hart Creek district, having his business headquarters on Guyan river, at the mouth of Big Hart creek. His prices are the most reasonable and the business very extensive. Hart, Lincoln county, West Virginia, is the post office address of Isham Roberts, Jr.
