How to color-code
You have four grandparents. Assign each grandparent a color so you can keep them straight!
All the ancestors of one grandparent will be organized under the same color:
Grandfather's lineage on your father's side: BLUE
Grandmother's lineage on your father's side: GREEN
Grandfather's lineage on your mother's side: RED
Grandmother's lineage on your mother's side: YELLOW
