I'm interested in learning about my Russian heritage and about the name Petroff. My father's name was Eugene Petroff (Pete or Sonny as he was called), born 11/28/1937 in Marianna Pa to Anne Marie Bolderoff? and Michael Petroff. My father died when I was 5 years old on 4/8/1972 at age 34 from cancer due to exposure to Agent Orange from his service in the Vietnam war. Anne Bolderoff Petroff died in 1989. I believe Michael Petroff has died because he was about 20 years older than Anne. I met him 1 time when I was 8 yrs old and he was elderly then (about 1974.)I've been told that his family was from Russia (near the Caucacus Mountains?) and emigrated to the US to escape persecution during the early 1900's. I know Michael Petroff had at least 3 other sons from a subsequent marriage in Erie Pa, but I don't know their names. Can anyone help? I want my son to know his heritage. Thanks.
