Affluent doesn't begin to describe it. Both his maternal and paternal families are very old money and, as noted before, he and Marie Caroline have ancestors in common.
Leopold's family owns his country's largest distillery (some world famous rum they make), sugar plants, a bank, and insurance company, etc.
His paternal great-great-grandfather, Vicente Lecuna Salboch, was one of his country's great intellectuals of the 20th century- an engineer, banker and historian who was president of the Caracas Chamber of Commerce, member of the National Academy of History and a member of the Academy of Physical, Mathematical and Natural Sciences, as well as a restorer, organizer and curator of the Simón Bolívar Archives, a rebuilder of his birthplace and editor of his documentation. After his passing, a three-day national mourning period was declared.
His mother seems to work at the Vollmer family foundation. His father lives in Miami (his linkedin shows he had an important job within Barclays for many years). Depending on the source, Leopoldo has either 5 or 3 more siblings
