So here's my guess on what happened. When I originally migrated my documents to the new MacBook (using time machine) it seems that the documents folders populated properly until a folder that had some protection on it. Today I manually moved the folder contents from my old MacBook into the empty folders on the new MacBook and I saw that the first folder required me to enter an administrator password to move the contents. I am thinking that the Time Machine migration must have aborted when it hit that situation. So its likely the documents never were there in the first place, and because I rarely look to these folders, I had wrongly assumed they had properly migrated, and suddenly vanished.
Thanks agin for the response.
