I'm looking for a Walter Bojanowski who recently died in Detroit in 2001. His wife was Shirley North. He resided on Rosemont in Detroit and was born in 1917. Have found no info on him in the census but as to your questions;
Junction is still in existence. The cemeteries close to that street are Holy Cross RC Cemetery on Dix Ave. in Detroit and Woodmere which is a few blocks away from Junction. This is the west side of Detroit where Poles migrated to. Most resided on the East side and the heavy duty Polish cemetery is actually Mt. Olivet and Mt. Elliot. Mt. Olivet is located on Van Dyke and if you give them a call, they will search their records. It may be better to write the Mt. Elliot and Woodmere. Holy Cross will give you answers right over the phone.
Junction area had many Poles and Hungarians.
Hope this helps.
Linda
