If you have not already discovered them, ancestry.com has at least 4 records for Oldrich Suchanek, including his arrival 15 Mar 1939 in New York aboard the "S.S. Isles de France". He departed from Southhampton, England to come to America and Canada. If you look at the passenger manifest it shows a little more information about Oldrich. Also, he flew from Toronto to New York 7 Aug 1946 aboard Trans-Canada Airlines. There is a record for a voting list in Canada and a departure passenger manifest from the UK for the 1939 voyage; however, I only have the domestic subscription and can't view those 2 records. At any rate there are some records for your timeline.
