New Idea: Complicated Family Tree

Pay attention to this, because it really is complicated.
I named it "New Idea", but I might as well have said "New Challenge":

1. Man1 has two daughters, each from a different mother
2. Woman1 has two daughter, each from a differen father.
3. A couple (Man2 and Woman2) have a daughter together
1. The man of the couple already had a daughter with another woman(3).
4. The couple gets a divorce
1. Man2 is now a couple with Woman1
2. Woman2 is now a couple with Man1
1. Woman2 and Man1 have a son together

I think that's a really complicated challenge to make this family in game.
