I would say it is what your budget will allow. However, I have a large family and we found that it was best to give to charities and give the donation in honor of our families. Then we created a letter for each family member and said that we made a gift in their name and the reason why we selected that charity.
You could also decide to have an immediate family time to exchange presents before the whole family gets together.
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.
