You have to count relationships from the common ancestor. In this case that isn't the brothers, it's their father.1. FP's 2nd ggf (aka your son's 11th ggf)2. FP's ggf and your son's 10th ggf3. FP's gf and your son's 9th ggf4. FP's father and your son's 8th ggf5. FP and your son's 7th ggf6. Your son's 6th ggf7. Your son's 5th ggf8. Your son's 4th ggf9. Your son's 3rd ggf10. Your son's 2nd ggf11.Your son's ggf12. Your son's gf13. Your son's father14. Your sonThe first generation is the common link between FP and your sonThe second generation were brothersThe third generation were first cousinsThe fourth generation were second cousinsThe fifth generation were third cousins - so that's the last generation with a direct "cousin" relationship. From there, every generation is one removed6 - 3rd cousins once removed7 - 3rd cousins twice removed8 - 3rd cousins 3x removed9 - 3rd cousins 4x removed10 - 3rd cousins 5x removed11 - 3rd cousins 6x removed12 - 3rd cousins 7x removed13 - 3rd cousins 8x removed14 - 3rd cousins 9x removed15 - 3rd cousins 10x removedSo after 15 generations, they are third cousins, ten times removed. If you're looking for a chart, here's one that doesn't extend out 15 generations, but it will help him visualize it: http://genealogy.about.com/library/nrelationshipchart.htm
