"du" means "from," "plessis" refers to a woven type fence or enclosure.
Du Plessis just means "from the woven fence" while plessis is... the thing itself. Is it fancier to be *from* the fence, than the fence itself? I personally don't think it's a particularly fancy name either way.
As for first names, my guess would be that
Marie du Plessis was a fairly generic name at the time (it still is where I live), which would have allowed her some anonymity. I have no idea how common
Alphonsine was, but I like it a lot. My favourite form of Violet-names is
Viola, but
Violetta is gorgeous, long in an elegant way.
Marguerite is my favourite version of
Margaret.
