Paulus den Bleyker family of Kalamazoo, Michigan. Papers of Paulus den Bleyker, his son John, John's wife, Anna Balch den Bleyker, and other family members relating to family and business affairs.

The collection includes the correspondence and business papers of Paulus den Bleyker, papers of his son John den Bleyker and John's wife Anna Balch, Paulus' daughter, Martha, and other family members and descendents. Much of the correspondence is in Dutch, but an English calendar of these letters (in box 1) has been prepared by Harry DeVries and Effa Zwier.

Many of the papers for the years 1828-1851 are on affairs in Holland and the den Bleyker settlement near Kalamazoo. For the years 1851-1856, the correspondence deals with personal affairs, the building of a flour mill and a saw mill and land transactions. For the years 1856-1857, there are many letters from family and friends but the bulk of them concern den Bleyker's real estate dealings. For 1872 to 1936, the correspondence is of John and Anna Balch den Bleyker and relates to family and business.

Of special significance in the collection is the file of letters exchanged between Paulus den Bleyker and A.C. Van Raalte, the founder of the Dutch community in Holland, Michigan.
