Call for Information: Russell Maloney

In Comments, Ken Nettleton seeks information on a prominent New Yorker contributor from the past:

Have a very elderly friend whose husband was a Harvard friend of a Russ Maloney (sp?) or Mahoney who worked at the New Yorker and was a contemporary of EB White. His wife’s name was Miriam who was an actress. Belief Mr. Maloney/Mahoney died from an anurysm after he lost his wealth in a failed musical. Would like to find some record (if any) of Mr. M’s writing and what ever happened to his daughter after his wife remarried.

Russell Maloney (not Mahoney) is credited with 387 items in The Complete New Yorker between 1931 and 1948. The vast majority of them are Comments or Talk of the Town items, both of which were unsigned for many years, I believe. So the occasional Profile or short story notwithstanding, it’s likely that readers were not aware of his large impact on The New Yorker in its formative first decades.
According to Wikipedia, Maloney wrote the book and lyrics for a 1948 Broadway musical of The Legend of Sleepy Hollow, which must be the “failed musical” Nettleton mentions. According to Time Magazine, he died in 1948 of a cerebral hemorrhage.
Miriam Maloney is credited with four Talk of the Town items herself. Can anyone help Mr. Nettleton discover what became of their daughter?
