Solving the puzzle of Henry VIII
"The precise number of miscarriages endured by Henry's reproductive partners is difficult to determine, especially when various mistresses are factored in, but the king's partners had a total of at least 11 and possibly 13 or more pregnancies. Only four of the eleven known pregnancies survived infancy. Whitley and Kramer call the high rate of spontaneous late-term abortion, stillbirth, or rapid neonatal death suffered by Henry's first two queens 'an atypical reproductive pattern' because, even in an age of high child mortality, most women carried their pregnancies to term, and their infants usually lived long enough to be christened.
"The authors explain that if a Kell positive father impregnates a Kell negative mother, each pregnancy has a 50-50 chance of being Kell positive. The first pregnancy typically carries to term and produces a healthy infant, even if the infant is Kell positive and the mother is Kell negative. But the mother's subsequent Kell positive pregnancies are at risk because the mother's antibodies will attack the Kell positive fetus as a foreign body."
