I won't design it for you. I don't get any grade.

Don't think of it as wills and people. Just think of it as things. Some of the requirements you have listed are things. Some are descriptive properties of things. List out what you think the things are and list out the properties of those things. That's step one. Step two, figure out what the relationships are between the things. Are they one to one (might be that you're looking at a property of a thing then), one to many (parent to child or primary key to foreign key), or many to many (the relationships can run lots of ways, for example any one will can have lots of bequests to lots of people, therefore requiring an interim table to map them together). Lay all that out to get started.

Then, if you have a specific question about the details of the work you've done, I'll be happy to help out, as will others here.
