My father's half-brother, Lyman Schambach, enlisted in the U.S. Army in 1904. After 1905, all documentation came to a dead-end. However, I have a lot of documentation from the Canadian Army in 1918 relating to the death of a James Murphy who was killed in action in France. I knew he had to be related since these documents and letters named my father's half-sister and included correspondence addressed to my grandfather. Both Lyman and James had the same date of birth, and listed their place of birth as Missouri so I suspected Lyman and James had to be one and the same person.
On Lyman's profile in my Ancestry.com tree, next to his name I put (aka James Murphy). When I did this, an Ancestry Hint popped up. To my surprise, there was another document from the Canadian Army confirming Lyman Schambach had used an alias name of James Murphy. I may never find out the real reason why he changed his name, but at least I now have a document confirming that he used an alias name.
