What is the relationship between Yu Yixiu and Yu Zhou?

There is no substantive relationship between the two.

Like Yu Yixiu, he is also regarded as Mr. Yu by many people, but in fact he and Yu Yixiu only share the same surname. To put it bluntly, he is neither the same clan nor a different surname.
