I don't think there is any connection (timing doesn't sound right) but I have been trying to research my family background as you are. I have heard wilczewski is not that uncommon in Poland. I found that (my family came to the US around 1898. Three brothers who were orphaned shortly after there arrival. They left New Jersey ( story has it that one brother broke out of the orphanage, found the other two and took them to live with some relatives in Pennslyvania but I haven't found much else about them. Their father was named Cashmir Wilczewski, and I think he is the one who died soon after arrival. My Uncle has done a great deal of research and I am trying to help him dig up what we can.
