BALKIEWICZ is probably a surname of polish nobilis living in historical Lativia (Litwa, Wielkie Ksiestwo Litewskie) - it was confederated with Rzeczpospolita (Republic) Polska (old Poland) about 1365 and it was very big - today its Lativia, Belorussia and Ukraina. So, Mr. BALKIEWICZ could make their village people free and give them his surname and sign (adoption). It was very popular way in XIX cent. in cause of russian law - only nobilis could be a free man. It is possible, that BALKIEWICZ is transformed from BIAL`KIEWICZ (where `L means a letter like british currency symbol), you can read it as <BIAUKIEWITSCH>. But I am not a genealogist too and I can missed. Name GRUNWALSKI is probably of german origin GRUNWALD - "a geen forest". The same name has a village where polish (and litvanish) king WL`ADYSL`AW JAGIEL`L`O has in 1410 a great victory upon a... I don't know english transcription... Priests of Holy Maria (I know its wrong, like my english at all - sorry) did you understood? It was the biggest battle in Europe that time. BOBROWSKI is a surname containing word BOBR - its an animal I don't really know its english name - it lives in rivers and cuts trees to build artificial lakes - now you know :)))))). Regards T.
