The Pannebakker Family Association is an outgrowth of the family reunion held at Pennypacker Mills, Montgomery County, Pennsylvania on July 2-4, 1999. The reunion celebrated the 300th year wedding anniversary of Hendrick Pannebecker and Eve Umstat, in Germantown, Pennsylvania in the year 1699.

In the words of the Steering Committee of the reunion, “We hope that the 1999 Pfannebecker-Umstat Reunion will lead to the growth of a family association, which will provide a forum for conversation, collection and preservation of information, and a sense of lasting community among the heirs of this rich cultural heritage.”
