Rosko Family History

Hungarian (Roskó): nickname for a red-haired man of Romanian origin (see Rosca). Slovak and Rusyn (from Slovakia) (Roško): habitational name from Roškovce in the Zemplín region in eastern Slovakia or a Slavicized form of Hungarian Roskó (see 1 above).

Slovak and Czech (Roško): perhaps a hypocoristic derivative of roh ‘horn’ or of the personal name Roch 1 Latin Rochus. Croatian (Roško): probably from a pet form of the nickname Rošo ‘red-haired’ (see Rosic) or its cognate Roso.

Alternatively, of the same origin as the name in 5 below. Croatian and Serbian (Roško): from a pet form of personal names beginning with Ro- (see Rodich) or containing the syllable roš such as Juroš (from Croatian Juraj ‘George’).

The surname Roško is very rare in Serbia, and in Croatia it may alternatively be of Hungarian origin (see 1 above). Compare Roscoe.
