Question:

What does the german last name Elert mean?

Best Answer - Chosen by Asker: The Ancestry.com report on the name indicates that it is a variant spelling of Ehlert and that name's meaning is:

Ehlert
North German: from a Germanic personal name composed of the elements agil ??edge??, ??point?? (of a sword) + hard ??brave??, ??hardy??, ??strong?? or ward ??guard??.

so something on the order of "brave point". or "hard edge"

There is a real spike in immigration of Ehlerts in the 1880s and in the 1920 census most of them are in PA, aside from being farmers in the 1880s the two other major occupations are commercial traveller and cigar manufacturer.
