As early as 1718 the Oertwig name, sometimes spelled Ortwich, was found in the village of Nahausen, near Koenigsburg in the Neumark area of Brandenburg, that portion that lay east of the Oder River in what is now Poland.

One of the families that remained in Germany was that of Gottfried Oertwig, who married in 1746 to Dorothy Filter. Family of Gottfried Oertwig

There are several groups of Oertwig families in the United States. Most of them are related, though at this time, the connections are not all established.

This page, listing the immigrant heads of families, serves as an index of sorts to some of the various lines. If you have corrections, or any more information on these or other Oertwig families please contact me! Thanks to Arlene Dudley, Linda Hanabarger, Emily Jordan, David Knecht, and others who have contributed information.
