Your query is a bit of a shot in the dark since you cannot even verify a country of origin. Even if they are ethnic Germans, you need a point to start from and that would require at the very least a parish name or better yet a village name of origin. A Google search does not turn up any Vindright surnames. I doubt that it is Germanic.
My best guess is that these families are Jewish. Jews did not use surnames until mandated to do so by Napoleon in the late 1700s. They often adapted or adopted some surname that often sounds ethnically German, Polish, Russian, etc. Therefore you cannot determine a place of origin on the basis of their current or recent surname.
I think you need to do more research this side of the pond before branching out to other countries. If you find they are ethnic German from Russia, return here with more questions. If they are ethnic Germans, you will need to find another forum for their specific point of origin. If they are Jewish, you may find more help at www.jewishgen.org
