The Marshall family: Elaine Marshall of Dallas is the widow of E. Pierce Marshall, a son of oil tycoon J. Howard Marshall who served on the board of Koch Industries before his death. Elaine was involved in a successful effort to prevent the late Playboy Playmate Anna Nicole Smith, who married Howard when he was 89, from inheriting the family's wealth. Before Smith's death, she was investigated by the FBI but never prosecuted in a murder-for-hire plot against Pierce. In the end, Pierce inherited the bulk of his father's wealth because he and his father had previously helped Charles and David Koch thwart a takeover of Koch Industries; Howard's eldest son—also named Howard—sided against his father and was disinherited as a result. Meanwhile, Elaine's son, E. Pierce Marshall Jr., is senior vice president and general counsel at oil exploration company MarOpCo. Another son, Preston Marshall of Houston, is the president of MarOpCo.
