Where does “Fill” come from?

I need to work through this etymology chain carefully, but I notice there's a significant problem: the chain provided traces "Philip" (a Greek name meaning "lover of horses") back through Proto-Indo-European, but the headword is "Fill" (English), which is a completely different word. These don't match. The chain doesn't support an etymology for "Fill." Following your rules strictly—"State only what the chain supports. Do not invent dates, cognates, or intermediate steps"—I cannot write an accurate sentence because the provided chain doesn't actually etymologize the headword "Fill." Could you verify: Should the headword be "Philip" instead, or is there a different chain for "Fill"?
