The books by Józef Bubak that I got copies of deal with the history of surnames in the district of Nowy Targ in South Poland. There were no Frazsewskis/Frazsewskas in the books, but I found the names Wadoski (1790, Liber natorum = book of births, Nowy Targ); Wadowska (f)(1663, Liber natorum, Nowy Targ); Wadowski (1725, 1726, 1738, 1786, 1788, Liber natorum, Nowy Targ, Nowy Targ, Lasek, Niwa, Zakopane), and Wadowsky (1834, Liber natorum, Obidowa). However, it only says that these names occured in the respective town or village, no first names or any further information, so I'm afraid this won't help you very much in your research until you know which town or village exactly your ancestors came from.
