As for the Wohling surname, I'm not so sure, but most of them seem to live in the areas of Luneberg, Germany. The German form is Wöhling, but perhaps it is related to the surnames Wolling, Wollinger, Wohlinger. Perhaps also related to Wollin, a place in Germany, but when looking for the Wohlin surname, without the g, it is a Swedish surname. hmm...
