says

Nibert
German: variant spelling of Nibbeling, a variant of Nebel.

and

Nebel

German and Jewish (Ashkenazic): from German Nebel ‘fog’, ‘mist’, Middle High German nebel. This could be a nickname, or alternatively a habitational name from any of several places so named in Schleswig-Holstein and Bavaria. In some cases it may be a shortened form of the Germanic personal name Nibelunc, Nebelung.

Altered spelling of German Knebel.

and

Knebel

from Middle High German knebel ‘peg’, ‘stake’ and, by extension ‘ankle’, ‘uncouth person’, this latter connotation is found particularly in southeast German and Silesian dialects.
diminutive of Knabe.

I didn't click on Knabe or even start on Braun. Give a person a fish and all that.

Answer 2

Nibert is from the Schleswig-Holstein, Bavaria area of Germany which my ancestors are as well. The name means 'fog' or 'mist.' You were correct about the Braun. Brown hair, eyes & or coloring.
