I have been conducting research in the Brabant area of Belgium for several years now, and both names are very common in the area near Huldenberg and Overijse. In addition, large numbers of Belgians from that area emmigrated to Wisconsin. Unfortunately, I do not have many inviduals with either name in the lines I am researching.

You may want to try and look up the families in the book by Les and Jean Rentmeester, "The Flemish in Wisconsin". It is long out of print, but may tell you something about them. Check for an interlibrary loan.

As far as if your ancesters were married before they came over, my guess would be not. In the early to mid 1800's it was common for most men and women to wait until their late 20's or early 30's to get married. While not everyone followed this pattern, the majority did. I would look into the early marriage records for Wisconsin to find their record.

Best of luck,

Tom
