I believe that the James White enumerated below is my husband's great-great grandfather, because his occupation is "saddler" and he is living in the presumed county of his birth (Brooke).
1850 Census - Brooke County, Virginia (now West Virginia)
United States Census, 1850
William Marks M 44y
James White M 23y
The 1860 and 1870 censuses below are definitely the census returns of Jim's great-great grandfather, because Jim's grandfather, Fernando, is enumerated with him and Fernando is an unusual name for the Ohio/Pennsylvania area. James White was born in Virginia (now West Virginia), which is consistent with the James White found in the census below.
In 1860 James White was a "saddler" as he was in the 1850 census above. In 1870 James White was a "harness maker" and in 1880 he was listed as a saddler again.

Sarah White died March 4, 1897, in Pittsburgh, Allegheny Co., Pennsylvania. There was a James White, born "June 1830" in Virginia, a widower with no occupation, living with Renwick and Cora (White) Denholm in 1900 in Pittsburgh as a boarder; I believe it is the same James White who is featured on this blog.
