^A descendant, Lt. Col. Robert Baylor Shackelford of the U.S. Army Medical Corps (Ret.), published an extensive genealogy of the Shackelford family, which was printed in Charlottesville, Va., in 1940. He retained the English genealogist Anthony Wagner (later to become Sir Anthony Wagner, Garter King of Arms and one of the world's leading authorities on heraldry and genealogy) to trace the ancestry of the immigrant Shackelford. Shackelford printed the genealogy with Wagner's findings, chiefly that Shackelford's immigrant ancestor came from the English middle to lower classes, that the immigrant ancestor's uncle was a butcher (and not a knight), and that no Shackelford had been granted a coat of arms in England. Despite results that some clients might have found disappointing, a solid friendship formed between Shackelford and Wagner, who traveled to Virginia to vacation at Shackelford's home in Albemarle County.
