No apparent attempt was made on the life of Irish-American mobster John M. Dunn, who later became brother-in-law of mobster Edward J. McGrath and a powerful member of the Irish Hell's Kitchen mob, after Schultz's death, discovered he and his wife had never been through an official wedding ceremony.
With the possible existence of another wife came with the discovery of letters and photos of another woman and children among its effects, in that in the hotel where he was staying in Newark. This was never resolved as his common-law wife refused to talk about it and the mystery woman never came forward.
Two other women also called the morgue to receive their effects, but their identities were never established.
