French haha. French term attested 1686 in toponyms in New France (present Quebec); compare modern Saint-Louis-du-Ha! Ha!. Usual etymology is that an expression of surprise – “ha ha” or “ah! ah!” is exclaimed on encountering such a boundary. In France this is traditionally attributed to the reaction of Louis, Grand Dauphin to encountering such a feature in the gardens of the Château de Meudon. English term attested 1712, in translation by John James of French La theorie et la pratique du jardinage (1709) by Dezallier d'Argenville: (Wiktionary)
