In addition to "no shortcuts" and Kalamazoo County GenWeb, etc., check out the Mayflower Families Through Five Generations book, Volume Twenty One: John Billington. This book, like others published by the General Society of Mayflower Descendants and referred to as "silver books" because of their color, documents the first generations. Once you can get your lineage back far enough to connect, it will point the way to the rest of your ancestors. Many libraries have the silver books.
Also, the Kalamazoo Public Library https://www.kpl.gov/genealogy/
and the Western Michigan Genealogical Society are helpful sources: http://www.wmgs.org/
