William's DC is very precise that his father Jacob Stout was born in Cambridge, PA, and his mother Sarah Toalston was from Snow Hill, MD. It also states that he was born in Ohio whereas the 1850 and 1860 census records give that he was born in Illinois.
There was also a county biography giving his father's death date and his grandfather's name.
There's a bio of W. B. Stout in History of Columbiana Co, OH and Representative Citizens, Ed by William B. McCord, Salem, OH, Biographical Publishing Co, Chicago, IL, 1905, p 540. It identifies his grandfather as Daniel Stout.
W. B. Stout, general merchant at Kensington, was born in 1850 and is a son of Jacob and Sarah Ann (Toalson) Stout. Daniel Stout, the paternal grandfather, was born in PA and in pioneer days came to Ohio and settled in Carroll County, There Jacob Stout was born. He died in 1852. [Note this does not say where W.B. was born nor where Jacob died.]
Our subject was educated in Columbiana County, for his mother moved to Salineville after the death of his father. Formerly Mr. Stout owned a farm of 72 acres in West township, but this he sold in the spring of 1904. In 1900 he entered into the mercantile business at Kensington, having previously been engaged as a clerk in other establishments. He thus had made many friends prior to starting for himself and now does a large and satisfactory business.
In 1889 Mr. Stout was married to Ella May Rhule, who is a daughter of John Ruhle, formerly a farmer in Wayne township, now deceased. Mrs. Rhule still resides on the homestead. Mr. and Mrs. Stout have two children, Byrell and Etura. Both he and wife are members of the Presbyterian Church. Politically he is a Democrat. He belongs to the Odd Fellows and to the Maccabees.
I think after his death his widow Ella Stout married George Leach 9 Nov 1921 in Mansfield, Richland Co, OH. I could not find a DC for Ella Stout.
The History of Columbiana County has an article on B. R. Stout that says that his mother now lives in Los Angeles, CA.
