I keep forgetting to mention that valde is "very" in Latin and those who wrote in Macaronic Latin/German often added German endings to Latin words, so there is some possibility that "valde[n]" might be Latin.
If the figure-8 is an "s" rather than something like "d"...
In old low German, walsen can mean to roll. The letters "w" and "v" were often used interchangeably in old German.
