I have a Dierk (Dirk) Dierks in my husband's ancestors, but he goes back to 1626 in the same area of Germany as your Dierk Dierks. Most of the family had moved by the mid-1700s to Oldenburg, Schleswig-Holstein. Our line comes from 1. Dierk Dierks b 1626 m to Aleke? 2. Juergen Dierks b 1652 in Gruppenbuerhen, m 1686 to Gretje Alers d 1710 3. Gesche (Margaretha) Dierks b 1706 who married a Juergen Doelling and had a son Markus Doelling. That's where our line of Dierks ends, but perhaps your family ties into our Dierk Dierks from 1626. Let me know if you make a connection.
