First cousins are people who share a grandparent. So your dad's cousin Martha has a grandmamma or grandpapa who is also you dad's grandmamma or grandpapa. Your relationship to Martha is cousin once removed. Your relationship to Martha's children is second cousin.

To simplify things...the short answer is "second cousin."

The children of your dad's cousins are your second cousins (any children of cousins make 2nd cousins)
