Swoboda & Nemec in Omaha, NE

I am new to gen. and CGSI – I am looking for relatives in and around Omaha, NE.

My greatgrandfather/mother, Frantissek (Franz – wagon maker, b 1839) and Anna Svoboda (b 1840), left thru Bremen on 20 April 1880 and arrived in NY on the SS Neckar on 28 or 29 May 1880 with 7 children: Antonie (b 1866), Barbara (1868), Josef (1870), Anna (1872), Franz (1874) Edward (1877 – my grandfather who had a printing company in Omaha in the early 1900’s called Colonial Press and that my father, Arthur Swoboda, ran until he retired in the late 1960’s) and Vircinc (1880). They came from Dobrnic, Caslau district of Bohemia. Anna Svoboda and 3 of the children (Antonie, Barbara and Josef) were born in Vrbic, Bohemia.

I do not know yet what year they arrived in Omaha, nor do I know what route they took from NY to NE, just looking for aunts, uncles or cousins.

Thanks!
