Hoover was a lifelong
bachelor, and there has been speculation and rumors that Hoover was
homosexual, but no concrete evidence of these claims has ever been presented. Such rumors have circulated since at least the early 1940s.
It has also been suggested that his long association with
Clyde Tolson, an associate director of the FBI who was also Hoover's heir, was that of a gay couple. The two men were almost constantly together, working, vacationing, and having lunch and dinner together almost every weekday.
Some authors have dismissed the rumors about Hoover's sexuality and his relationship with Tolson in particular as unlikely,,
,
"The strange likelihood is that Hoover never knew sexual desire at all."

while others have described them as probable or even "confirmed",,
</bgref>
and still others have reported them without stating an opinion.,
</bgref> Attorney
Roy Cohn, an associate of Hoover during the '50s investigations of Communists and himself a closeted homosexual, opined that Hoover was too frightened of his own sexuality to have anything approaching a normal sexual or romantic relationship.
Hoover's biographer
Richard Hack reports that Hoover was romantically linked to actress
Dorothy Lamour in the late '30s and early '40s, and that after Hoover's death, Lamour did not deny rumors that she'd had an affair with Hoover in the years between her two marriages. Hack additionally reports that during the '40s and '50s, Hoover so often attended social events with Lela Rogers, the divorced mother of dancer and actress
Ginger Rogers, that many of their mutual friends assumed the pair would eventually marry.
In his 1993 biography
Official and Confidential: The Secret Life of J Edgar Hoover,
Anthony Summers quoted a witness who claimed to have seen Hoover engaging in cross-dressing and homosexual acts on two occasions in the 1950s.
Summers also claimed that the Mafia had blackmail material on Hoover, and that as a consequence Hoover had been reluctant to aggressively pursue organized crime. Although never corroborated, the allegation of cross-dressing has been widely repeated, and "J. Edna Hoover" has become the subject of humor on television, in movies and elsewhere. In the words of author Thomas Doherty, "For American popular culture, the image of the
zaftig FBI director as a
Christine Jorgensen wanna-be was too delicious not to savor."
Most biographers consider the story of Mafia blackmail to be unlikely in light of the FBI's actual investigations of the Mafia.</bgref>
Hoover has been described as becoming increasingly a caricature of himself towards the end of his life. The book, "No Left Turns," by former agent Joseph L. Schott, portrays a rigid, paranoid old man who terrified everyone. For example, Hoover liked to write on the margins of memos. According to Schott, when one memo had too narrow margins he wrote, "watch the borders!" No one had the nerve to ask him why, but they sent inquiries to the Border Patrol about any strange activities on the Canadian and Mexican frontiers. It took a week before an HQ staffer realized the message related to the borders of the memo paper.
African American author Millie McGhee claims in her 2000 book
Secrets Uncovered to be related to J. Edgar Hoover.
McGhee's oral family history holds that a branch of her Mississippi family, also named Hoover, is related to the Washington, D.C., Hoovers, and that further, J. Edgar's father was not Dickerson Hoover as recorded, but rather Ivery Hoover of Mississippi. Genealogist George Ott investigated these claims and found some supporting circumstantial evidence, as well as unusual alterations of records pertaining to Hoover's officially recorded family in Washington, D.C., but found no conclusive proof. J. Edgar Hoover's birth certificate was not filed until 1938, when he was 43 years old.
