From the February, 1919 Issue of Erie Railroad Magazine:

CORPORAL ROBERT S. GRUNDEN
Word has been received from the superintendent of the Marion division to the effect that Robert S. Grunden, a corporal in the 166th U. S. Infantry (Rainbow Division), died on Oct. 8, 1918, of wounds received in battle October 1. He was a student clerk at Ohio City, under Erie Agent Harriman at the time of his enlistment during the Mexican trouble, and was with General Pershing. After the demobilization he was again called to the colors at the outbreak of the late war, and was in France since September, 1917. He had been gassed and wounded, and had been over the top several times. He was 21 years old at the time of his death.
