In 1900 you had 76 million people, that included 12 million Roman Catholics of whom almost 2 million were Poles (source: Wacław Kruszka, "A History of the Poles in America to 1908").
I'm pretty sure you had some Catholics even already back in the 1600s.
But Estonia and Latvia are mostly Protestant, could those areas have so many Catholics?
