From Find a Grave:
According to the WWI Military Service Card at NYS Archives: "Zygmunt Baranski," Army Ser. No. 105,333, resided at 51 Perrin St, Auburn, NY. He enlisted in the Regular Army at Camp Syracuse, NY on June 26, 1917, was born in "Garbor [Garbow], Poland," 23 years of age upon enlistment.
His units of assignment were: Co A, 38th Infantry, June 27, 1917 to Aug. 13, 1917 4th Tng Co Battalion, 16 Infantry, Dec. 16, 1917 Co A, Machine Gun Battalion, 1st Brigade to --- [dashes on record] Co A, 2nd Machine Gun Battalion [1st Division] to death
Baranski attained the rank of Pvt on enlistment and was promoted to Pvt 1st Class on Nov 1, 1917. He was killed in action on June 7, 1918 and notification of his death was recorded as being made to his brother, Joseph Baranski, of 1627 Hawley Ave, Syracuse, NY.
Baranski is featured in an article in The Auburn Citizen on November 11, 1919, entitled "Those Who Fell": "From the reports of many in the city, Zygmunt Baranski, who was member of the First Machine Gun Company, A.E.F. was among the first of the Auburn men to be killed in action. The date of his death June 7, 1918. Baranski, who formerly lived at 51 [?] Perrine Street, Auburn and was a member of the Polish Falcons, enlisted in Syracuse, so the exact date and regiment is unknown. He has no relatives living in the city, but has a brother residing in Syracuse."
Additionally, a profile of Baranski was included in Auburn, New York's World War I Memorial Booklet, May 26, 2003:
"ZYGMUNT BARANSKI, 24, Single. Native of Garbow, Poland. Immigrated in 1911. He is survived by a brother Joseph in Syracuse. His occupation was shoemaker with Thompson-Whitmore. He was a member of the Polish Falcons. He had told his brother that the wished to avenge his father's death (a Major in the Polish Army) who was killed by the Austrians earlier in the war on the eastern (Russian) front. Buried in the Somme Cemetery, France."
Zygmunt Baranski is listed as one of ten men who "Died in Action" on the Syracuse, New York Memorial in Kosciuszko Park "Dedicated to Polish Legion of American World War Veterans of Onondaga County" as "Z. BARANSKI." Though from Auburn, it may be that his name is on the Syracuse memorial through the efforts of his brother, Joseph Baranski. Joseph lived in Syracuse and had been a member of the Polish-American community there and it's likely that he requested Zygmunt's name be included on the memorial. The memorial was dedicated on May 26, 1935 by members of Syracuse's Post 14, "E. Jablonowski," of the Polish Legion of American Veterans ("Syracuse Honors Memories of Heroes: Tablet to Polish-Americans is Unveiled," The Syracuse Herald, May 27, 1935).
