Genealogy / Want to find a person [755]

Ludno Poland. My grandfather and his 3 brothers were born there. Wolfe, Jack, Max and Harry Cohen. My grandfather Wolfe was born March 8, 1885. I assume the 3 brothers in the late 1880's. My grandfather went to England and married Ethel Ward, they ran a shop until they moved to Canada as did the 3 brothers. I am having trouble finding information from their time in Poland and I know nothing about Ludno, if they still have relatives there. Wolfe and Jack became furriers, I know nothing about Max and Harry.

Any help is greatly appreciated.
