body: I remember reading a case years ago where a woman named Sharon Corr sold a product called "Corr's Ginseng Up." (Adolph) COORs (a beer company) sued for trademark infringement and lost. 
  
  
  The two names were similar but the woman WAS using her own name. 
  
  
  In another [case](http://www.leagle.com/decision/19971493965FSupp528_11426/HAVEN%20CAPITAL%20MANAGEMENT%20v.%20HAVENS%20ADVISORS), an investment firm called Haven Capital Management tried, and failed, to prevent a woman named Nancy Havens from naming her investment company after her own (maiden) name.
  
  
  Under what circumstances might a company with an established brand prevent someone from using their own name?
  
  
  
title: Can a trademark supersede or preempt a person from using their own name?
