Definitely possible, though my paternal line came out of northern Mississippi, not the delta.
Most people think of the Mississippi delta as being the Mississippi River delta. But the state of Mississippi’s Delta region is the northwestern part of the state. All the little creeks and rivers flowing into the Mississippi River get sluggish and swampy in delta-like conditions. “The Delta” is just south of Memphis and north of Vicksburg.
