My name is Olia Hladun. I am of Ukranian decent. My mother immigrated to the U.S. in the early 60's. I don't know much about my father, I believe his name was Walter Hladun or Wolodymr Hladun. I know he was born in Europe, any more details I have never been told. I think he died in the late 70's of choking while eating, definately in Yonkers, New York. He was married to a woman with children when having an affair with my mother. I am looking for whatever information can be provided, I'd like to learn about my father and his ancestry. I believe when his children were young, he lived with his wife in Manhattan. I am 30 years and I believe he had 2 children from his marriage, boy & girl. I don't remember much and my family is not very supportive, they keep my family history a secret. Any help would be appreciated!!
