Lukasz:
I am embarrassed that I missed Julius Christian C. Sosnowski, who was not a member of the Hampton Legion, but was a member of General Marttin W. Gary's brigade staff.
His sketch is as follows:
SOSNOWSKI, JULIUS CHRISTAIN C. Initially appointed Assistant Surgeon and assigned 2 Louisiana Infantry 6 July 1861, to rank 18 Sep 1861, age 20. Assiugned to 3 Louisiana Infantry 18 Sep 61; resigned 14 Nov 61; enlisted as Private in Co. B/Holcombe Legion (S.C.) Cavalry Battalion at Columbia, S.C. 20 Nov 61; detailed as courier for MGEN Gustavus W. Smith and MGEN Arold Elzey, each commanding Department of Richmond Dec 62-Dec 63;appointed Ordinance Sergeant of 19 Virginia Heavy Artillery Battalion 12 Jul 64; on staff of LCOL John C. Pemberton, commandign artillery, Department of Richmond Dec 64; paroled as Ordinance Sergeant Gary's Cavalry Briugade at Appomattox 9 Apr 65; medical doctor; son fo Madam Sosnowski (who operated Madam Sownowski's Girl's School, at Barhamsville, near Columbia; resident of Columbioa prewar; married 1867 and settled on Edisto Isaldn, S.C.; born Erie, Pennsylvania 1841; died of diptheria at Edisxto Island 21 Aug 76; buried Trinity Episcopal Church, Edisto Island.

My endnotes state that Sosnowski was unfit for field service, apparently as a result of disease, and he was on detail from December, 1862 until the end of the war. He married postwar and settled on Edisto Island, the home of his wife. See Sosnowski Scrapbook, South Caroliniana Library, University of South Carolina. His death is noted in the Charleston News and Courier, 22 Aug 1876, page 4. He was the son of Joseph Stanilaus Sosnowski, who was born in Lithuania of an old Polish noble family. Serving in the Russian army, the elder Sosnowski joined the Polish revolutionaries in the Revolution of 1830, and was forced to flee when the revolution collapsed. He arrived in the U.S. in 1833, and first settled in Erie, pennsylvania, where his four children were born. Following the death of the elder Sosnowski in 1845, his mother moved to take a series of teaching jobs, first to Troy, N. Y., then to Charleston, S.C., then to Macon, Georgia, and finally to Columbia, S.C., where she founded the Barhamsville Institute for Women near Columbia in the mid-1850's. Madam Sosnowski's school, was patronized by some of the best families in the South. See Edmund L. Kowalczyk, "A Polish Family in the South," Polish-American Historical Assocxiation Archives.
