There are quite a few Wesselings in Friesland. If you are interested in Dutch genealogy try "GenLias" which is run out of the Rykesarchyf in Leeuwarden(translation: State archives). All you have to do is register(free!) and then type in your surname. It will pull up all birth/death and marriage records dating from 1811. You get direct on-line access to the records, which, unfortunately, are in Dutch.
Frank there are lots of Dutch Wesselings. Use the Gen Lias registry available on-line. You will probably find the person you are looking for. My parents emigrated from Holland after the war. My father's family is from Friesland, the Netherlands.
