Ok, not directly on topic but since you are into 'research' and this is in the scandals section:
It might be interesting to find out how many times this scenario plays out:
Brother marries widowed sister of means, they together make a 'conditional donation' to the Society's conditional donation arrangement (funds are all hers from previous marriage). Unbeknownst to wife, husband allows that in event of HIS death, funds go directly to Society. Sister only finds this out upon husband's death - TOO LATE! Society already has funds....
