Volume 23 of the Tennessee Valley Genealogical Society's publication included a story entitled "A Man Named Sam, A Boy Named Dred,". by Norman M. Shapiro, which indicated that Dred Scott once lived in Madison County, Alabama, when he was young.
According to the article, Mr. Shapiro was first aware of the Dred Scott connection to the Peter Blow family when scanning a book about Southhampton County, Virginia. He learned that Sam Blow, later known as Dred Scott, was born near Edom in 1809...northeast of where Nat Turner resided. [See the Marker in Southampton]
In 1816 Peter Blow and slaves moved to Huntsville, Alabama, and then in 1823 moved to St. Louis, Missouri.
