Grandparents and cousins family tree

A grandparents-and-cousins family tree makes the connection between two branches of a family easy to see. The shared grandparents sit at the top. Their adult children form the second generation, and the children of those adults form cousin groups in the third. Add partners next to the relevant adult child, then place each cousin group underneath. This structure is useful when a family wants to document close extended relatives or explain a relationship at a gathering. It also makes a good starting point for a broader family history, because each branch can be extended later without changing the generations already drawn.
