A shocking treasure trove of Kennedy documents, photos – and even a human brain fragment believed to belong to former president John F. Kennedy – have been found in the attic of the late Sen. Ted Kennedy's Hyannis Port home, The ENQUIRER has learned.

The stunning discovery came when workers cleaned out the historic Cape Cod, Mass., house, which originally belonged to Joe and Rose Kennedy, to begin preparations to convert it to a museum in 2009.

"There are some incredible things in the boxes, safes and lock boxes that have been gathering dust for many decades," a longtime family adviser revealed to The ENQUIRER.

One of the most unusual items found in the attic is a tiny fragment of a brain preserved in formaldehyde.

"The family knows that Bobby Kennedy was given part of JFK's brain after his autopsy, and that it was not buried with him," said the family adviser.

"Bobby may have meant to have it cremated or something. Most likely he was assassinated before he could do anything with it."

Also found in the attic were letters written to Kennedy family patriarch Joseph Sr. by Nazi leaders during the time that the elder Kennedy was serving as the U.S. Ambassador to Britain
"They had the Nazi seal, an eagle holding a swastika in its talons, on each page. They are written in German script and even bear the lightning strike symbol of the SS," divulged the adviser.

"It certainly looks like Joe had closer ties to Hitler than had been previously thought."

Among the more heart-wrenching finds were boxes filled with drafts of letters that Ted had written to the family of Mary Jo Kopechne, but never sent, revealed another source.

The young woman died in the infamous 1969 Chappaquiddick accident.

"Ted was tortured over Mary Jo's death and forever sorry for the terrible pain her family suffered," divulged the source.

"On a number of nights he would sit out on the deck of the house drinking Scotch and trying to write a letter apologizing to her parents.

"One late night he told me, 'There is no point trying to explain away my behavior. I want to say something to make them feel better, but I can't find anything.'

"He wrote that he felt so vile about it, he had considered suicide numerous times.

"He kept most all of those letters, thinking one day the right words would come to him.

"As far as I know, they never did."
