Having many siblings should not scare you from creating an all-inclusive-family tree. The 4 generation family tree template accommodates siblings at every generation.
You can only add a sibling to the template by adding at least one parent first. In other words, the sibling should be linked to a parent to prove kinship. Notably, direct blood relatives make the family tree core. However, if you have half-siblings, you can connect them by a horizontal line stretching out from the blood parent.
Adding relatives in the 4 generation family tree helps you visualize your extensive lineage. Besides, the four generations display a clear relationship throughout the family structure.
