On my grandfathers immigration papers from 1908 I have learned that my KEIDEL family is from Muhlheim, Germany. I have been told it is on the river Eis in Bavaria. I cannot find this river on any atlas to help identify which Muhlheim they are from. My cousins father told him it was more of a creek than a river. Has anyone ever heard of this river? Thanks in advance for any possible clues. Betsy researching Keidel Heintz in Germany
