A family unit chart is a tree showing all the members of a family, especially children and parents, who are considered a single entity in society. Normally, the unit chart has the eldest generation at the top and the younger ones at the bottom.

The first best practice when creating the family unit chart is to include dates and full names. Also, conduct in-depth research about possible genetic conditions and any other identifying characteristics. Remember to label each generation using roman numbers, so the generation at the top would be generation I.

Creating a detailed family unit chart will not only help connect with your heritage but also trace any family health or genetic concerns.
