I wish I could help you, but I have been unable to find that information myself. So far, all I have is John's birthdate and the 1880, 1900, 1920 and 1930 Census information. I believe they married between 1910 and 1920 because the 1920 Census is the first that have them listed as married. My information shows her name as Anna G, but that is all.
You might try to contact William McCloskey from his McCloskey Family Tree. He is very good about sharing his information
