Summers also found evidence that blacks referred to Hoover as "some kind of spook'' and even "soul brother,'' and realized that in some black communities in the eastern part of the USA, it was generally believed that Edgar had black roots. Hoover's ancestry was always a subject of speculation within the FBI, because of his lack of documented heritage that was always required when someone joined the FBI. Wesley Swearingen, a former FBI Special Agent (from 1951 to 1977), and author of the 1995 book FBI Secrets: An Agent's Exposé, said that it was always viewed as a mystery the lack of documented evidence on Hoover's background:
"Because for all the FBI agents, they'd go back and check everything about your family, your relatives, and everything else, to make sure they're squeaky clean . . . and here, the Director, and nobody knows really where he came from . . . agents would get into topics like that where they on a surveillance or something, when they finished the crossword puzzle, and had nothing else to do, and they'd start talking about Hoover . . . all the agents would get onto the subject of his real tight hair, his tight, wirey hair, and speculation that maybe there was a little hanky-panky in his family . . . and then his facial characteristics were really unusual"
Spannaus has done excellent research himself, which along with McGhee, have also confirmed that there are substantial discrepancies concerning Hoover's early biography. He observes how:
Strikingly, there does not appear to be {any} contemporaneous record of Edgar's birth in Washington. Hoover's own autobiographical account - on which virtually all biographers have relied - states that he was born January 1, 1895, at his parents' home on Seward Square, in the Capitol Hill neighborhood of Washington, D.C., with a physician, Dr. Mallan, in attendance.
However, despite the fact that it was legally required to report a birth to the District of Columbia Health Department, and that this had been done for the first two children born in the family (Dickerson, Jr. and Lillian), there was no certificate of birth filed for Edgar by Dr. Mallan.
The entry for John Edgar Hoover in the Washington D.C. index of births was clearly added at a much later date, and the certificate number contains the suffix "D'' - signifying a delayed filing.
