There are so many spelling variations of all surnames it's confusing. You don't know whether the
individual, a family, or some half-literate census taker wrote it down the way he heard it from
someone speaking in a heavy accent from the olde country.
Pertaining to Ehlers - I found some in my line who served in the CSA under the name spelled
Eller.
I'd assume they're all related until proven otherwise. If not, you're going to miss someone.
Good hunting,
Love, Lou
