Eschelman is usually the Americanized version of Aeschlimann. The only sure way to find out if Christian E is a descendant of Peter A (from Langnau, not Langau!)is to find out what the place of origin of Christian E is. In Switzerland people are listed after their family's origin and not where they were born. Originally all the Aeschlimann's are from the Emmental region but from different communities!
