Lloyd was born in Caledonia, Michigan on the 23rd of May, 1889, and while I am not sure what brought him to California, it was there that he enlisted in the Army National Guard’s 7th Infantry in January of 1906. When he deployed to France for the Great War, he was a Sergeant with Company F, 364th Infantry, 91st Division and his actions on the 26th of September, 1918 earned him the Medal of Honor. The citation reads:

Suffering from illness, Sgt. Seibert remained with his platoon and lead his men with the highest courage and leadership under heavy shell and machine-gun fire. With two other soldiers he charged a machine-gun emplacement in advance of their company, he himself killing one of the enemy with a shotgun and capturing two others. In this encounter he was wounded, but he nevertheless continued in action, and when a withdrawal was ordered he returned with the last unit, assisting a wounded comrade. Later in the evening he volunteered and carried in wounded until he fainted from exhaustion.

Lloyd received the Medal of Honor from General Pershing on the 27th of January, 1919 and he remained in the Army. He was a Master Sergeant when he was appointed the rank of Warrant Officer in August of 1937 while at Fort Knox, Kentucky with the 1st Cavalry (mechanized), and would retire from the Army at the rank of Chief Warrant Officer. Lloyd Martin Seibert died on the 15th of October, 1972 at the age of 83 and is buried with his wife, Augusta, in the San Francisco National Cemetery in San Francisco, California: Section OS, Row 128, Site 10.
