作為命理網的學術研究，探討美國人的日柱是哪一根，建議挑選現代人，而且出生日期沒有疑慮的命造。

以美國聯邦調查局（FBI）第1任局長胡佛為例，他的生日就是有疑慮的。1895年，華盛頓DC已經規定報戶口要提供出生證明，胡佛的兩位兄姊都有配合提供，但奇怪的是，胡佛本人的出生證明卻遲至1938年，在他43歲時才提供，證號字尾多了一個D字（delayed）。

學者另外發現，胡佛13歲在教會受洗的洗禮證書顯示，他是1895年6月1日出生。當胡佛在1938年9月提供出生證明建檔時，同時也收到當初受洗教會提供的洗禮證書（原牧師筆跡的6月，被另一個筆跡改成1月）。

The Mysterious Origins of J. Edgar Hoover

Who Was J. Edgar?

With his interest piqued by McGhee's account, this writer has confirmed that there are substantial discrepancies and oddities concerning J. Edgar Hoover's early biography.

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.

This writer obtained a certified copy of Edgar's actual birth certificate--which was not filed until 1938, when Hoover was 43 years old! The verification of birth is provided by an affidavit executed by Edgar's older brother Dickerson N. Hoover, Jr., who states that he was present when Edgar was born, and that he himself was 15 years old at the time. Oddly, Dickerson's affidavit does not mention a doctor being present, in contrast to Edgar's own account.

(Curiously, Hoover never applied for a birth certificate until after his mother's death in February 1938. It seems obvious that his mother--if she in fact was his mother--would have been by far the best witness, rather than a 15-year-old boy.)

John Edgar Hoover was baptized at age 13, during the time he was under the tutelage of his brother Dickerson, who took him from one church to another, looking for the most prestigious congregation. The church baptismal record, obtained by this writer, lists his date of birth as June (not January) 1, 1895.

A question also might be raised as to why Edgar was not baptized until age 13, since the various churches with which his family was associated (Catholic, Lutheran, and Presbyterian), all practice infant baptism.

About the same time that Hoover's birth certificate was filed, in September 1938, he also obtained a letter from the church, certifying his baptismal record. The letter also gives Edgar's date of birth as June 1, 1895, with ``Jan.'' written over ``June'' in an obviously different hand than the signature of the church's then-current pastor.
