Let's say I have an account Smith Family. And that I will also have various companies that work for them entered as accounts:

- Pool Cleaner

- Landscaper

Etc.

What is the best way to relate those accounts to Smith Family, preferably with a field that explains the relationship.

It's important to note that the pool cleaner and landscaper would also need to be able to be associated with several other accounts in the same way.

Thank You
