Does Jeffrey Epstein have a secret son or daughter to inherit his vast fortune? That's what a DNA company is trying to answer. Morse Genealogical Services sent out a call looking for the "unknown children of late Jeffrey Epstein" or anyone who believes they gave birth to his child. Epstein was never married. He did have a younger brother, as well as a niece and nephew. Depending on the deceased person's will, relatives would inherit everything. But that could all change in Epstein's case.
