We have a funny situation in the Norwegian side of the family. Apparently both of my paternal grandfather's grandfathers were named Ole. So when my grandfather was born, he was named Ole after one grandfather. And then along came a brother who was named Ole after the other. And then they had a sister. Clearly the parents had run out of imagination by then because they named the daughter Oline. As we Norskie-Americans often say, uff da!
