Are there really names that are considered specifically Flemish? When I googled it, links seem to indicate that there are, but they might just be calling them Flemish because they're used in Flanders-- rather than referring to the language itself.
I've always wondered about this because my husband's grandmother is from Antwerp and she speaks Flemish. But her name is perfectly English (or would work in French, too), and I unfortunately don't know any other names from her side of the family.
