Jay,

Thank you for sharing your polygraph experience. If you could contact me privately, I can share some information that might be helpful in persuading your family not to rely on junk science like the polygraph for any important life decisions. I would also be willing to speak with you and your wife together regarding the unreliability of polygraphy. You'll find my contact information in my signature block.

You should know that you are far from alone in being falsely accused of deception about marital fidelity by a polygraph operator. There are many posts similar to yours on this board. See also the personal statement "How I Failed My Polygraph Exam" provided by Gary Smith.
