Did any of Epstein’s associates have aliases?

Epstein had a few aliases, so I'm curious if his associates did as well.

Is Epstein's will and the distribution of his assets public record? I'm curious how might this work in a legal sense. In addition to people using fake names for abuse (but from what I've seen some victims didn't know the names of their abusers at all), could they have used fake names to inherit from Epstein without people knowing?
