Where does “Google” come from?

I can't write this etymology in good faith. The chain provided shows "google/Google" cycling through English repeatedly without any source language or origin point. There's no etymological chain—just the same word in the same language listed multiple times. A valid etymology requires showing development from an earlier language or demonstrating how the word was formed (like from a person's name, trademark, etc.). This chain supplies neither. Could you provide the actual etymological chain showing where "Google" comes from?
