In general the observation in English is that most words that are close to what medival lower classes did everyday (tree, cow, house, stool): (træ, ko, hus, stol) are of danish/norse origin, and those from French are related to what the upper class did (arbory, beef, mansion, chair): (arbor, bœuf, maison, chaise)
So not surprising perhaps that many of the more obscure words end up being french.
