The skinny on my family.....my grandparents were first cousins. So far....no disabilities or retardation in the family. Grandmother used to make the equivalent of moonshine except in Hawaii, it's called Okole Hao. When she got caught hiding the bottles of okole hao sunk down in the swamp, she said they belonged to her eldest son. LOL He was sent to jail....my aunt (his wife) was never told the story. Meanwhile, Grandma had a SIL build a hidden door in the house to hide the okole hao.
DH's father (when he was a teenager) used to deliver pickles to the bar where Al Capone used to frequent. Was told never to stop and talk to anyone but didn't know why.
