because of the way your surname is spelled in English it would be "Juszewski" in Polish
I agree. The spelling of Youshefskie/Youshefskie suggests that someone intended to preserve the exact sounds of the Polish name (rather unusual in the USA), so Juszewski would likely be the original name. However, there is also Juszczewski which to an American ear would sound very similar to Juszewski. Currently, the are no Juszewskis in Poland, but there are 6 Juszczewskis. Juszewski is from personal names starting with Ju: Justyn, Julian, Józef. Juszczewski from the name Just, from Latin Justus "just;" also from Celtic Jodocus, Judocus.
