While keeping his surname fixed, Kellogg was very changeable about his
first and middle names and initials. Back in the late 1930s, when he
began seeking work as an actor, he was known as "Giles Kellogg" and
"Giles V. Kellogg" (in "Academy Players Directory" and acting on
Broadway), the "V" standing for "Vernon". Later, once he began getting regular film acting jobs, he
changed to "John Kellogg" and "John G. Kellogg", the "G" standing for "Giles".
