A memorial service for former Michigan first lady Helen Milliken will be held June 3 in Traverse City.
   Son Bill Milliken Jr. says the service is to take place in the Milliken Auditorium at Northwestern Michigan College's Dennos Museum. 
   Helen Milliken was the state's longest-serving first lady and a staunch supporter of women's rights and the environment. She died in November at age 89.
   A reception will follow the memorial service in the museum's Sculpture Court.
