In the big family genogram diagram below, we start by mentioning Grandparents from paternal and maternal sides, including multiple uncles, aunts, brothers, sisters, siblings, distant cousins, and more. It should be noted here that creating a big family genogram and a big family tree are two different diagrams. As the big family genogram looks like a family tree, but with all the different types of relationships, it contains a significantly more detailed and complete picture of the family or group it illustrates. You can use this big family genogram diagram to understand more about the family history, medical conditions, future aspirations, etc.
