As Bruno already said, there isn't a town or a village with the name of WIC in the whole of France. There is a very small village (in french "un bourg") with the name of Wicres on the road of Lille to Bethune in the Nord of France, even not in Picardie.
It can't also be in the neighborhood of Nancy because in France all the towns and villages held their independance since the French revolution.
It is neither a part of Nancy - this you can see clearly if you visit the website of Nancy --- www.nancy.fr
I can't make only one conclusion - your source must be wrong.
