If I understand you correctly if the dad is claiming the daughter then you cannot claim her, but if the woman is living with you then you should claim head of household and she could be on yours. That's up to you! The dad cannot claim her if she doesn't live with him.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
