I searched on Blauvelt at WikiTree but so far I couldn't find any Blauvelt here yet. :)
I saw you already started a Free Space for another One Name Study. Otherwise I would suggest you start it yourself and wait and see. Of course you can start multiple One Name Studies.
My experience is when profiles of a particular name are added, after a while, more interested will follow, as they search for the name at internet.
Another way is to tag Blauvelt to your list at your profile hoping more will follow.
I hope you will get some support here Christine!
Kind regards from the Netherlands,
