You could request the death certificate for Gussie Deutsch from the NY City department of Health, but i believe that a person needs to be a direct descendent of the deceased to do so.

You might have better luck requesting the marriage license for the couple, and the 1901 birth certificate for the first child Helen, from the Luzerne PA county courthouse/Register of Wills-Clerk of the Orphan Court. Though with the pandemic going on, that might take longer to be processed. Those would have the maiden name of Gussie Deutsch, and possibly her birthplace:
