53 Ancestors in 53 Weeks - #5 Frederick William Kosack

Frederick William Kosack was born in November 1842 in Prussia.  I still don't have exact date of birth for him. He I my Paternal great grandfather and the immigrant ancestor.  He came to the United States in January1859 and arrived in Baltimore, MD.  He arrived on the ship  JOHANNES along with his mother Caroline, brothers Otto and  Leo, sisters Mathilda (Bertha) and Augusta.  Another brother Edward was already here in Baltimore.

Frederick, Edward and Otto joined the union army in Baltimore, Maryland September 1861.  Frederick was a private in Co. K, 2 Reg't Maryland Infantry.  His last name has various spellings while in the military.  Kosack, Kossack, Cossick and Kosak.  He was discharged with a medical problem  February 1863.  He returned to Baltimore but was living in Bladensburg, MD in the 1880 census.

He married Augusta Wanda Kleinstuck, who I profiled last week, 25 July 1876 in Washington, DC.  Frederick was a woodcarver by trade.  He died 28 March 1911 of TB and is buried at Rock Creek Cemetery in Washington, DC.

My goal is to find out exactly where they came from for sure.  There are several different notations as to various places where the family originated.
