Corporal Clifford C. Wiltshire (1896-1918) resided at 1022 Avenue P, in Brooklyn, worked on Park Avenue, in Manhattan, and died for his country in France.
On April 6, 1917 while he was working as a private secretary in the home of William Thaw on Park Avenue, the United States declared war on Germany. That very day, Clifford C. Wiltshire went directly to the 7th Regimental Armory at Park Avenue and 67th Street, to enlist. On August 25, 1917, the Army reassigned 332 men of the 7th Regiment to the 69th Regiment. Many famous New Yorkers belonged to the 69th, including the influential Roman Catholic priest Father Francis P. Duffy (1871-1932) and poet Joyce Kilmer (1886-1918), both of whom have Parks named in their honor.
