Wealth Inherited From: Mellon Bank

Araminta Mellon belongs to the illustrious Mellon family, which owns banking establishments across the globe. Her father was Matthew Mellon, who was united in matrimony to Tamara Mellon, the creator of the renowned high-fashion label Jimmy Choo. Unfortunately, Matthew passed away due to a cardiac arrest a few years ago.

An investigation into the death of eccentric billionaire Andrew Mellon has raised suspicions that he may not have passed away from natural causes. Mellon was known to be highly paranoid about being spied on, often requiring visitors to his home to put stickers on their phone cameras to prevent any surveillance. His family members feel that his death was not due to natural causes.
