This is believed to be a photo of Cornelius "Neal" Pierce (b. 1874), who lived in both Mobile County, Alabama, and adjoining Jackson County, Mississippi.
Note Neal's suit, double-breasted vest, and small loose bow tie. This style of dress was common between 1889 and 1895. Neal looks to be around 20 years old in the photo, so that would place this image as having been made in the 1890s.
Neal and other members of the Pierce family often crossed the Alabama-Mississippi state line over their lifetimes to farm or work in the rural communities.
Did you have ancestors who lives on both sides of a county or state line? Did that cause problems trying to track them in census records?
