Thanks for your response. Unfortunately, I don't know a whole lot more - but what I do follows:
Stephen (Stefan) Woloszyn (or Volosin) was 26, according to his marriage application. He had just been married several weeks before he was killed, and he may not have even known that his new wife had become pregnant. The following November, his only daughter Anna was born to his wife Marya (also known as Maria or Mary, with her maiden name having several different spellings such as Krehil and Krechlów). The pregnant Maria had married again several months after her husband's death; the second husband's name was Martin Moraskie.)
Stefan was originally from Muszyna, Poland, a small town in the far southeast of the country only a few miles from the Slovakia border. This area was also referred to as "Austria" or "Galicia" at the time. Stefan may have only been in the United States for about a year, as I found a passenger record that matches his name, approximate age and plausible destination that shows his arrival as April 1899.
Coincidentally, just this past week I had a conversation with my wife's aunt, who told of a grisly story that after the accident, Stefan was brought back on a stretcher (in several pieces) and laid on his kitchen floor, as "visitations" at the time were held in the family home.
That is about all we know of Stefan. Thank you again.
