The following titles are listed in our db, but I can't match them to any of the twelve identified Nelsons.

Any idea?

• Bloodsuckers Disc 2
• Civil War Journal: The Commanders
• Flag of our Soldiers (The Boys of H Company)
• The Hillz
• The Hillz - Bei mir zuhause (The Hillz)
• The Munsters" Scary Little Christmas
• Suits on the Loose
• What Becomes of the Broken Hearted?

There are many C. Nelsons out there. The outcome of the search for their common names and needed BYs are presented here:
