Research gaps: Very little public information. Forbes (Sept 2026, net worth ~$32.2B, Dallas) is the only source for the ~16% Koch, Inc. stake, inherited from late husband E. Pierce Marshall (d. 2006), whose father J. Howard Marshall II was an early partner of Fred Koch; sons Preston Marshall and E. Pierce Marshall Jr. Forbes says Pierce Jr. runs 'Elevage Capital Management'; an SEC-registered adviser 'Elevage Partners, LLC' (Reno, NV, SEC 801-112475) exists but its link to the family was not verified, so it is left out. Koch, Inc. (renamed from Koch Industries) is private and publishes no shareholder data; rename date not verified. No SEC CIK found for Elaine Marshall. No real estate, trophies or recent deals verified. The Stern v. Marshall caption on LII does not print Elaine's first name, so her role as executrix is not stated here.
