This map shows the landscape of Landkreis (district) Mayen-Koblenz and the surrounding area. My 4th-great-grandfather Nikolaus Schneider was stationed in Koblenz when he was in the Gendarmerie. He moved to Remagen after he married. Although Remagen is located in Landkreis Ahrweiler, it is also shown on the map.
