Family of Murad IV. Its terrible to see how many of his sons just died as infant. Evliya said that all his sons were born with poor health, so I guess it was some kind of genetical disorder, because otherwise we cannot explain the death of this much young baby. Seems like his daughters were not involved as they mostly reached adulthood or at elast died as kids (which was unfortunatelly normal back then). Handan Sultan, Sultan Ahmed I and Murad IV themselves also had poor health and died young, probably Murad inherited it from Handan and Ahmed and for some reason in his case it went through and reached his sons also? I dont know but it is interesting... We know that there are genetical disorders which effect only boys.
