The list of assets included 36 pages of bonds, eight pages of blue chip stocks, and $31 million in a non-interest bearing checking account. Her will was found in a tin cabinet with four bars of soap. She gave just $5,000 to her closest genetic relative, a cousin, but the court awarded her $140,000 during probate. The rest was divided between 63 charities and educational institutions.
