Thayer's Note:

a So the apparent unanimity of Web sources, but his actual birthdate may be April 29: the law mandating an officer's retirement on his 64th birthday was taken to the letter, as can be verified in many entries of the Register — and here (q.v.) the Register records that Gen. McCook was "Retired from Active Service, he being 64 Years of Age, April 29, 1895."
