 There is no record of Dred Scott's transfer to Sanford or of his transfer back to Irene Chaffee.John Sanford died shortly before Scott's manumission, but Scott was not listed in the probate records of Sanford's estate.Also, Sanford was not acting as Dr. Emerson's executor, as he was never appointed by a probate court, and the Emerson estate had already been settled when the federal case was filed.
