You may already know this, but in case you do not. Several years ago part of this Esch family still lived in Broken Bow, Nebraska. My Uncle Criss Ash talked to one of them to see if we were related. We are not unless it is way back. Our Esch were in Blessenbaugh, Germany in early 1700's.
The Custer County Historical Society in Broken Bow has obit's from the area by surname.
