In 1890, Adolph Espe arrived at New York aboard the S.S. Slavonia from Hamburg. One column on the incoming passenger list (but not on the departing list out of Hamburg) is headed Death and Cause of Death. In that column, for Adolph, someone has written "6-4." Does this mean that he died on June 4th? Or something else? Six other people on the list have numbers in that column but the ink and the handwriting for those numbers doesn't match most entries on the page. I'm attaching an image.
