Many other languages do. I think all Chinese languages do, but you don't need to go that far. Even German/Dutch/Frisian/Swiss do have it, although nowadays few use them and many people don't even know. (Father's siblings are Onkel/Tante cognate to uncle/auntie, but Mother's siblings are Oheim/Ohm/Öhi if male and Muhme/Muoike if female.)
