Many Dutch names and others have the same problems. Sometimes those who recorded the information put down what they thought they heard. Later this same thing happened for the large number of immigrants who came to this country through Ellis Island. I have seen Michaels, Michaelse, Michelsen, Mekeel, McKeel, Bastiensen, and even Louw-then Low for one group.. . perhaps others. These are just those descendants from Michiel Bastiensen Van Kortrijk. Those descendants from his brother Jan generally took the Kortright/Courtright name although there are variations there too. It does make research difficult. What is your line and how can we help?
