Does the name jacquest have any significant historical importance in france from the 1700's to the early 1900's?

So my friend acquired a big box of old photographs, books, and notebooks all containing some perculiur notes in an estate sale. A few of the notes were hinting towards some great importance in that bloodline and I'm wondering if anyone has heard of. This family might even have owned a castle at one point. The notes cut out after the note taker writes that he's thinking about going on an expedition to France to find more documentation. Any help at all would be deeply appreciated :)

Hi, if you don't get an answer here (or even if you do), consider x-posting to /r/genealogy: family history research is their bag, and they may be able to point your friend at some useful resources.
