Looking for Family Coat of Arms under the German name Frohreich

In which part of Germany (town or region) did / do they live? 
In which century?

From talking to relatives and from just plain looking up my last name
from some records i have come up with two places both from northern
germany and Prussia, some records show early 1900's late 1800's

You need to understand there is no such thing as a "family coat of
arms" in European countries or the British Isles. Ther are a number of
articles about this on the Internet, including

Eogn-ga, I do not quite understand your claim that "there is no such
thing as a 'family coat of arms' in European countries".

There are many families with the same coat of arms for all the members
of one particular family ("Familienwappen" in German). Of course, the
genealogical relationship should be established before claiming to be
a member of the family in question (i.e. the coat of arms in
question).

The question as asked by preist-ga referred to a family in Germany and
possibly this family did have a family coat of arms.
