Prof, would you like to rephrase this question?
If I answer “Not from a film set in the present (for when the movie was released), without being of the sci-fi, fantasy or horror genres,” it could have several meanings.

Did you sculpt Lincoln on a large scale? - Daniel Chester French, best known for this: Daniel Chester French - Wikipedia
Did your dad kill your childhood friend before your eyes? - Frederick the Great of Prussia (they’d tried to run away from the palace when kids)
A fictional youth, was your grandfather a retired cop? - Frederick Crane, on Frasier
“Was human, not any longer” made me pretty sure it was a horror movie character. Common first name with F is most likely Fred. Given the time frame, he seemed the most likely choice.
