Maureen has an amazing amount of information about her grandfather. Some time ago, I came across the description of James Mulvaney's heroism as a firefighter, rescuing a comrade from a burning building. Among the documents I received from Maureen was a letter from his chief commending his actions on that occasion. She tells me that he received the Henry Bookman Medal of Heroism, the second firefighter to be a recipient.
