looking for UNTERMANN surname in Bydgoszcz

I know the father of my grandfather was born in bromberg (bydgoczsz nowadays), I think 26 or 27 january 1877 and I also have two addresses but from Bromberg time. So, I want to know where I can have the equivalence between the name of the streets in the time of Bromberg and those of actual Bydgoczsz?
I know he left Poland and finally finished in Argentina, but I don't have any information of that time

Thank you very much,

Why do you need that ?

Because I have two addresses and I think they are more or less from 1877 or something like that and I think they are in german...
They are Friedenstrasse and Danzigerstrasse... I don't have very accurate the numbers of the houses but I know one was the house of the father of my grandfather and the other was the shop they had at that moment...
Just to know where it is, what happened with these properties, because they have to leave Bydgoczsz because of the war...
