Great grandfather

This is my great grandfather (my father's mother's father). He came to the United States from Turov, Russia (Belarussia). He became a citizen of the United States on June 6th, 1938 while residing at 520 Tinton Ave. in Bronx, NY. He never went to school and was unable to write his name in English, which is more or less how his last name was changed from Murofchick (I have seen numerous different English spellings) to Miller. He was a presser of clothes. He was married (1909) to Devorah (Dora) Bashkin before he came to the U.S.; they did not come here together, she came later. He was the son of Chiam Murofchick and Ida Rose (maiden name), both of whom died in the second world war. He also went by his hebrew name, Chone or Chunan. He passed away on November 11th, 1977 at 2:55 PM at Manhassat Medical Center in Manhasset, NY at age 91. The immediate cause of death is listed as acute myocardial infarction.

From what I can gather, his siblings were Sonia (Susha), Abe, Joseph, Nachman, Benny, Morris and Golda (who may have been married to Hyman's uncle Harry). His grandfather was Yudel Muravchick, and his great grandfather (my great great great great grandfather) was Avrum Muravchick. He had three daughters (one died in childhood) and one son. He had six grandchildren and twelve great grandchildren (at last count).

We all wonder what he is leaning on in this photo.
