Answer:
A blended family
Explanation:
The blended family is the family where grandparents live with grandchildren. This is also called a step-family or a constituted family. It is also called a complex family where both the parents live with their children from the previous relationship and now make a new family.
These parents live together with children from the previous relationship and current relationship. The parents could be from the same sex or maybe heterosexual and may don't have children.
Thus Josephine families are the example of a blended family where she got two half-siblings from the father side and a half from the mother side. They all live together called a blended family.
