Private Frank Sonsire (1889-1918) died in World War I at the Battle of Argonne. Born in Rome, Italy, on January 7th, 1889, Sonsire came to America with his mother Sadie, and moved to 233 North 5th Street, in Williamsburg, Brooklyn. He joined the U.S. Army on May 28th, 1918, and went overseas on July 9. As a private in Company D, 316th Infantry, he fought in France at Avocourt and Proyon, both defensive operations in the Lorraine sector. He died in action on November 9, 1918, near Bois de Consemoye, in the Argonne region of France—three days after Germany formally requested a truce and two days before Armistice and the end of the war. He was 29 years old.
