But not all her endeavours are separate from the family business. Sheila is an emeritus trustee of The Henry Ford, the museum complex that her family owns in the suburbs of Detroit. 

Her husband Steven Hamp (pictured), who reportedly boasts his own $3 million (£2.4m) fortune, is a life trustee of the institution, which boasts a number of Ford-related attractions across a 250-acre site.

Sheila also serves on the boards of The Ford Motor Company Fund and the Edsel & Eleanor Ford House. The Michigan mansion belonged to her grandparents and became a National Historic Landmark in 2016.
