There is a Theodore Hyzenski who was the son of John and Helen Hyzenski. Theodore was born around 1909. They came to the US in 1896-97 from Poland which was a part of Russia at the time. Thus you might see references to either Russia or Poland in looking them up. My research has found instances where the name's been spelled Hizynski (post WWII), Hyzenski (1920-1930), Hasencki (1910) and possibly Hezcyzynski (1896). All except the last one are confirmed to be the same family.
