Greg I also am a descendant of Christian Hubert Effertz and Mary Gertrude Esser. Gertrude's parents were Johan Joseph Esser and Anna Maria Schmitz. Johan came to America in 1869 with his second wife Apalonia and resided in Green Isle Sibley County Minnesota.They lived in the parcel next to a Peter Esser family that I have not been able to connect to our family.
