Details of the trial of German-born Rockefeller imposter Christian Karl Gerhartsreiter are being tightly guarded ahead of its start Tuesday morning in Boston's Suffolk County Superior Court.

Court officials tell FOXNews.com that a complete witness list won't be available before the proceedings begin. But some names have been leaked.

Here is a partial list of witnesses set to testify during the trial of the man calling himself "Clark Rockefeller," accused of kidnapping his 7-year-old daughter Reigh:

Dr. Keith Ablow — A psychiatrist, TV show personality, author and FOX News Channel blogger and contributor who had his own television program, "The Dr. Keith Ablow Show," from 2006 to 2007. In addition to being a regular on FOX, Ablow has appeared on the "Today" show, "Good Morning America," "The Oprah Winfrey Show" and numerous others. He writes a column for the New York Post and is a contributing editor to Good Housekeeping and Men's Fitness. He has written six mystery novels and eight nonfiction books.

Amy Jersild Duhnke — The first wife of Gerhartsreiter, whom he married in Madison, Wisconsin, in 1981 to get his green card. Divorce records filed 11 years later by Jersild, now remarried and living in Milwaukee, show that Gerhartsreiter left her the day after the wedding.

Sandra Boss — The most recent ex-wife of Gerhartsreiter, who was calling himself "Clark Rockefeller" when they married on Nantucket in 1995. The couple have a daughter together, 7-year-old Reigh Boss, whom Gerhartsreiter is accused of kidnapping during a supervised visit. Sandra Boss, who gained sole custody of Reigh, works in London as a partner at the global management consulting firm McKinsey & Co. She is on the board of The Mount, Edith Wharton's estate in Lenox, Mass. While married, the Harvard Business School graduate and "Rockefeller" lived in a posh brownstone and led a lavish lifestyle, buying a yacht and a summer estate in New Hampshire and associating themselves with society's elite. The 2007 divorce was brought on, in part, by the fact that Gerhartsreiter refused to reveal his true identity, according to court records.
