Hi,I couldn't find a Mr. Urquhart that was born in 1896 in the NARA site.There is a Mr. Urquhart that was born in 1895 that is listed in the Social Security Death Index as having died in 1972. He was born and passed in Wisconsin.
I'm no expert but I'm not sure that a man that was 44 would have been accepted into the military at that age.
Here is information from the Mormon Geneology site.It shows the same birth date you have posted and his parents.
Raymond John Urquhart
Birth:12 AUG 1896Boston, Suffolk, Massachusetts Parents: Father:John Mother:Nora
Is there any other information you can provide like where he was residing when he might have enlisted or been discharged, middle initial, if he died in the war?There are options to find more information than what the NARA site has so more information may provide more options.
