Lot of
@Uncle Tom Doug relatives in the crowd
Three of my cousins do have sickle cell trait.
Edit - It's more than three, I forgot about the the ones on another branch of the family. It's probably more like 8. Three are kin by blood, the others by marriage and the ones by marriage are 2nd cousins. Another fun fact, the ones that are kin by blood are white, at least in appearance. The two girls have blonde hair and grey/green central heterochromial eyes. The boy has brown hair and brown eyes. It's hilarious because their grandmother, the one we didn't share, was racism incarnate. She would have made Clayton Bigsby blush. The grandmother was elderly when they found out, so the family kept it from her because they thought her finding out would upset her enough to kill her.
