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.

FAQ

Common questions

How are cousins connected on a family tree?

Cousins are shown as children of siblings, with shared grandparents above both sibling branches.

Where do aunts and uncles appear?

They appear as the siblings of a parent in the generation above the cousins.

Can I add more cousin branches later?

Yes. Add a partner and children below another adult sibling while keeping the generation levels consistent.
