Julia,
Upon further review, I think the record is for the same person because the spouse mentioned in the 1861 marriage you reference, and the 1869 birth you reference, do match the same spouse listed in the death record. Also, the age of the deceased, Jonasz, matches the age for the same person listed in the in 1869 census for Jonasz of Tokaj, Zemplen county. 

Why does the town of birth not match the town of birth in the other records? I am not sure. If I could locate his tombstone for that date, it might give further clues.
