Frank A. Pinkos undertaker shows in the 1928 Detroit city directory as being at 3224 Junction, which is today a parking lot across the street from St. Hedwig's R.C. church. He also shows as having a combination furniture store and undertaking business at 8700 W. Jefferson, which would be somewhere near Delray but I must say appears to be a mystery address [[it seems to be somewhere in the middle of the Rouge River).

For several decades there was a Pinkos & Szwapa funeral home just a couple of buildings south of St. Hedwig's at 3311 Junction. That building is still standing, although the funeral home is gone. St. Hedwig's is still open, so if your aunt was Catholic you should probably check there.
