I found this interesting quote in Minnesota History, Volume 44 (St. Paul: Minnesota Historical Society, 1974), page 135:

Occasional pathetic ballads continued to appear into the second decade of the new century – songs of neglected children like "Lonely Little Refugee" (1914) and "Mister, Won't You Buy a Paper?" (1910) by Eleanor Langdon of Minneapolis, who also contributed a heart-touching number called "Write a Letter Home to Mother" (1913). More in keeping with the changing spirit of the times were such compositions as "Oh! Sam! I Envy You" (1911) by Harry DeRoe Jones, a Minneapolis piano tuner and one-time newspaper editor at St. Cloud and Chatfield, and "Thtop Your Thtuttering, Jimmy" (1919), a St. Paul-published World War I song by Hal Blake Cowles....

This publication is classified as "snippet view" by Google Books, so I wasn't even able to find the title of the article, but it seems to concern music published in Minnesota. WorldCat shows that The Minnesota Historical Society has the sheet music in its library. I still doubt that it's the song you want.
