Search idea at Google Books

There are many ways to search for things at in an attempt to locate genealogical information.
One approach is to try the names of an ancestral couple, either complete names or first and last names, using the maiden name for the wife.

For example:

Ufkes Grass
Johann Ufkes Noentje Grass

Tinsley Dunaway
Enoch Tinsley Nancy Dunaway

Might be worth a shot.
