Where does “Disney” come from?

I can't write this etymology in good faith. The chain provided doesn't support "Disney" as an English word—it traces "do/give" back through Latin and Proto-Indo-European, but Disney is a proper noun (a surname, then a company name) derived from the surname of Walt Disney, which itself comes from "d'Isigny" (from Isigny-sur-Mer in Normandy). The chain you've provided explains the word "de" or "do," not the etymology of the name Disney. To write an accurate one-sentence origin summary, I would need the actual etymological chain for Disney as a surname/proper noun, which would involve French place names, not Proto-Indo-European verbal roots. Would you like to provide the correct chain, or would you like me to demonstrate with a different headword that actually matches the given chain?

Disney (English): The Walt Disney Company, named after Walt Disney
