In 2008, Suzanne S. Bettac, professional genealogist, was engaged by Lucy Croft to research the Koenning and Wemken family lines. She contacted a representative of the Oldenburger Society for Family Research in the parish of Rastede (Germany) – Mr. Günter Oltmanns. He provided the name of a CD book of compiled records which firmly established several generations of direct ancestors of Helene Catherine Margaretha Wemken Koenning. The information is presented via pedigree charts on the following links.
