People always like to know who the famous people are in their family. I have been working on my inlaws family trees. I was trying to go back at least 5 generations for each of them so that my nieces and nephews would have more info than just the Mullins/Bentley side of the family. I did pretty well and only have a few brick walls.
When I come to a woman in the family and only her first name is known, I first try to identify her maiden name. Then I try to expand her family.
For the Schenck family, I have a Mary Gregg and a Phebe (probabley Phoebe) who I was researching. I have a guess that I am still working on for Mary, but Phebe is just a dead end. Then there is Sarah Couwenhoven who married William Janse Schenck. I had found her parents and grandparents. When I tried to document them, I found other researches who had different grandparents for Sarah, so I started over on her.
I found a website that took the Couwenhovens back several generations to the Netherlands.
You Schencks should take a look. It is www.conovergenealogy.com , it has a lot of your family history.

Generation 5: Obediah Schenck & Sarah Eleanor Scharff
Generation 6: John David Schenck & Mary Ann Gregg

Generation 8: William Janse Schenck & Sarah Couwenhoven
Generation 9: Jan "John" Schenck & Neeltje Eleanor "Nellie: Bennett
Generation 10: Jan Roelofse Schenck & Sarah Willemse Van Kouwenhoven
Generation 11: Roelof Martense Schenck & Neeltje Garretse Couwenhoven
Honing in on Generation 8 Sarah Couwenhoven
Generation 9: David Couwenhoven & Ida Garrett Wyckoff
Generation 10: Willem Albertse Couwenhoven & Lysbeth Benjamin Van Cleef
Generation 11: Albert Van Couwenhoven & Neeltje Roelofse "Eleanor" Schenck
Generation 12: Williem Gerretse Van Kouwenhoven & Jannetije Pieterse Monfoort
You'll notice there are Van Kouwenhovens in both lines. One of the marriages was of cousins.
The family came from the Netherlands in the early 1600's. I have the names of the ships and dates they immigrated.
But, going back to what I said, since folks are always interested in who they are related to who are famous, the website I referred you to had these folks as famous relatives of the Kouwenhoven family. Some could be the author's maternal line, but I will leave that for you to figure out if you are interested.
