two families where both fathers are brothers and both mothers are
sisters?
I found your question to be quite intriguing. The answer is that the cousins you describe are known as "double first cousins", or sometimes just as "double cousins".
An overview of less common cousin relationships can be found at on genealogy.com, at: http://www.genealogy.com/heard122800.html?Welcome=1028779582
Another interesting page from CousinCouples.com provides an overview of state laws regulating the marriage of cousins: http://www.cousincouples.com/info/states.shtml
Search Strategy:
A Google search for "fathers are brothers" "mothers are sisters"

Thank you for the opportunity to answer such an interesting question.
