Thomas W. Sigler was born in May of 1844 to Otho Sigler and Mary Jane Wheeler. Although records conflict as to whether Thomas was born in Virginia or Maryland, it is likely he was born in Maryland because, at age 18, Thomas enlisted in the 2nd Maryland Infantry, Potomac Home Brigade on November 1st, 1861. Thomas was a Corporal, serving during the Civil War. He served until January of 1864 when the terms of his service ended but re-enlisted one day later. He was ultimately “mustered out” in May of 1865 in Baltimore. Thomas never married and lived in Ekalaka, Montana, where he worked as a laborer. Thomas had a half-sister named Mollie Watkins. When he was 81, Thomas was admitted to the Battle Mountain Sanitarium in Hot Springs, South Dakota. He passed away due to chronic myocarditis on December 12th, 1926.
