You stated you have no evidence that Catherine's parents crossed the pond...........Both are buried in Pilgrim Home Cemetery on Ottawa coumty.....
The birth dates for the parents are on cemetery records which provide you info for further searching in the Netherlands.
Katie De Kraker at the samecemetery and passed in 1952..
Searching for the family of Catherina Sinke/Sinke who immigrated to the U.S. Catherina/Katie was born in the Netherlands about 1885. I have found no record of her parents actually living in the USA. I do find their names listed on their childrens marriage record.
