AND YES, we ARE kin to another famous actress through the Noblets:Mary Noblett. (Movie star known as Mary Castle. She was called "the Rita Hayworth Look-alike").Mary and Irene were 3rd cousins but may never have known it. LINK TO MARY:
As for Irene, she was a far more accomplished actress than a lot of people realize. I have seen her in movies in the 1940's with her 1st husband, Tim Ryan. Before movies, they were a famous radio comedy duet.
