Legitemacy is subjective in this case. Ofcourse you and I wont agree with it, and I personally feel every minor belongs with his/her mother unless there are exceptional circumstances. In some cultures, if the father dies, it falls upon the shoulders of the male head of the family to assume responsibility for any child/children the deceased had. Some might say, they are now "their" children.
