From the advice you already received and some checking, it is evident that your ancestral last name had many spelling variations. It would be useful for you to discover and evaluate as many of these spelling variations as possible.
You wrote the name as Jurison, but this quickly included Jurisin. It seems there were more people with the -in ending than with the -on ending. Sift through the Ellis Island records, by checking also for the start of the name being Dz or Gy which are all very similar sounds. In other words, check the USA arrivals with spellings Gyurisin, Dzurisin, Gjurisin, Djurisin and Gurisin.
There is one open question, namely, why was the starting letter (if it was J) not changed to Y in the USA. For me, this fact would tend to increase the probability that the name of your ancestral family was already spelt with a starting J, rather than Dz or Gy. In any case, look at the arrival records of people who had the first letter spelled with Gy, Dz and variations of these.
