I am a descendent of the Johannes/John - Jager/Jaeger family from Germany that immigrated to St. Charles County, Missouri in 1852. Two of the death certificates of father/son descendants from Germany reflect Gundheim, Kurhessen, Germany as their birthplace, yet what I believe to be the father's naturalization document reflects the location as Coehessen.
I have had no luck in trying to find a Gundheim city in Kurhessen (did find two villages in Rhineland), or confirm Coehessen is the same as Kurhessen? Does anyone know, or can refer me to a resource that might clarify the location?
